Is the PoE support on the switch the major upgrade on this one compared to the UDMP?
There seem to be other differences like 2.5Gbe WAN and integrated 128GB storage. I wouldn't be surprised if they internally discontinued the original and are just selling remaining inventory. The SE could easily become the only version they sell soon.

CONS:
Those 8x gigabit ports only have 1 gig backplane. It means you'll never get 1 gig speed if you use more than 1 port.
The 8x port are PoE (af) not PoE+ (at). It means it will not fully power most of their APs.

Holy crap, was about to order til I read the specs and came here to post. Only two ports are PoE+.
10 min ago I just opened my UDM Pro and Switch PoE, wanted to return for this.. guess that wont be happening.

PoE+ and a 2.5GbE RJ45 WAN port. There have been rumblings that there may be plans to allow WAN2 to be remapped as a LAN port, meaning two usable SFP+ 10 GbE ports rather than the single port allowed by the current configuration.
It also has a built in 128GB SSD which can be used for storing protect footage, though that won't give you much storage if you record continuously.
I have an EA version of the router, and during testing they upgraded ports 1 and 2 to 802.3at PoE+ (30W max per port), and it looks like that has carried over to the launch product. That is convenient, as it means you can power any of their access points directly from the built-in switch. The U6-LR requires PoE+, and the specs for the U6-Pro call for it, though it will function perfectly fine on 802.3af PoE (15.4W max per port) in my experience.

This is old, stunningly persistent misinformation. The 1G limit is only between the backplane and the WAN. LAN traffic never hits that and gets the same speed as any other [comparable] UniFi switch. Unless you have >1G internet service AND have multiple devices trying to saturate that connection AND actually care about such things, then yeah, maybe the UDMP isn't for you. For the other 99.9% of use cases, that 1G limit is about as meaningful as whether your Honda Accord can really peg its 140 MPH speedometer.

All 8 gigabit ports share 1 gigabit backplane. It sucks.
looking at the thread, it sounds like the switch itself doesn't have a 1Gb backplane, the routing SoC is between the switch and SFP+ ports, and is only connected to the switch at 1Gb, which will allow a max of 1Gbps aggregate between all 8 1Gb copper switch ports and any of the other (2.5Gb, 10Gb) ports. Which is also very dumb. Devices on the 1Gb copper side can all talk to each other at 1Gbps simultaneously.
If you have 2Gbps Internet service and expect to be able to utilize 100% of that on devices connected to the built-in 8-port switch, that's not going to happen. If you have another switch connected to the other SFP+ cage, yeah that should be okay.

Both points are not really accurate.
They added PoE+ to ports 1 and 2 during testing, which was a nice surprise.
For L2 traffic (data link layer), the built-in 8 port can switch at the line rate (16Gbps). You are limited here by the 1000BASE-T interface, of course, as on any switch.
Say you had a desktop (1GbE Cat6), a laptop (Wi-Fi 6), two phones (Wi-Fi 6), and a NAS (2x 1GbE Cat6) all on the same corporate network with a single U6-Pro access point
You could simultaneously:
transfer a large file from the NAS to the desktop at around 900Mbps
back up your laptop connected to AP 1 to your NAS at around 800Mbps
transfer a file from phone 1 to phone 2 at around 800Mbps
download a torrent from the public internet at around 700Mbps.
etc.
The 1Gbps backplane only really comes into play with L3 (network layer) traffic. For most people that just means the public internet or their work VPN. For more advanced home users, if you have multiple corporate networks on the 8-port switch or are routing between VLANs, the backplane is a 1Gbps bottleneck on that traffic.
If you are a normal home user with 1Gbps internet or less, there is no bottleneck. You can share that 1Gbps across multiple ports just fine, and the UDM Pro is a very powerful router that can route that traffic at full speed while performing resource-intensive processes like traffic identification/management and intrusion prevention.
If you want to share your 1440Mbps Xfinity among a bunch of different devices, you're right that you won't get more than 1Gbps in aggregate on the built in 8-port switch, which some high-end consumer/"gaming" routers with a 2.5GbE WAN or supporting LACP can do for multiple clients on Wi-Fi plus their built in GbE switch. You could put one device on the 10GbE SFP+ LAN port and use the full bandwidth that way, still limited to 2/3 of that bandwidth on the 8-port switch. If your network REALLY requires more than 1Gbps routing on multiple clients simultaneously, the Unifi Switch Aggregation[ui.com] is a very reasonable way to upgrade that bottleneck to 11Gbps at $269. If you want PoE+ RJ45 ports instead the Switch Enterpise 8 PoE[ui.com] is $479. Both are in stock

Yes, those reports are very overblown. Mine works flawlessly.

Isn't it dynamically adjustable with a budget?

No you're wrong. Please the thread and unifis detailed specs sheet.
The routing engine is limited to 1gb back plane to the switch backplane.
The switch backplane can run at full gigabit (full duplex)
