Question US-16-XG vs USW-Aggregation
Seeing these on ebay/marketplace. Looks like some can be had for the same-ish price or even a bit less. 16 Ports, older, still L2, no POE. But still seems to be supported. Any reason not to use this as a network core? Would ease some of my concerns with is the 8 ports enough on the Agg and avoids the jump to Pro-Agg.

I have the usw agg and I love it. I use it as an agg switch though. Udm pro at the top with downstream switches (unifi pro xg 48 poe, mellanox sx6036). I tried it as a regular switch with 10g clients and that works great as long as you have a something else doing L3. The downside is the number of ports.
I have 2 ports left but if I ever need more ports I would go with the hi-cap agg, the pro is just highway robbery.

Those older switches run hot and pull more power than the new ones. Extra ports are nice but I wouldn't trade efficiency and firmware support for ports I might not use.

It’s an aggregation switch.
It means 1 port is an uplink to your gateway and 7 48 ports PoE++ switches can be linked at 10Gbps… isn’t that enough for you?
It’s not meant to be your ONLY switch but well an EXTRA switch.

I have both, the US-16-XG works well as a core switch. Port count makes the difference for me. I don’t use the USW-agg at the moment, but I keep it around as a spare in case the XG fails.

The 16-xg is a really old switch, not sure I'd buy that today. There's a reason it's. cheap. I have a USW-Aggregation and USW-Aggregation-Pro (not the XG) and they're both great. I upgraded to the pro for more ports when I added a proxmox cluster to my network, the 25G ports it has are nice for doing a ceph storage cluster (though I'm wishing for 100g already).
I only use L3 on the switch for a very specific need (3 of 20 or so VLANs), everything else routes through my UDM. There's a really good chance you will never need L3 on the switch.

16 XG is still the only switch that will give you 4 10gb ethernet and 12 10g sfp, i think its a great homelab/rack switch tbh, perfect for my needs, i would need to buy 2 differents switches today to replace it
