2D multiplayer sync? about nature2d

As for now, Firing events is the only way, if the movements are basic, the bandwidth used won't be Huge. if you just fire one event with a metatable inside containing the info you won't have to spam multiple events every tick.
hope this helps

Okay, so what about colliding with the real 2D world if your 2D character is desynced from the server's physics?

Roblox (in 3D) can handle reactions to collisions of unanchored parts from players moving or one of their projectiles. Recalling from BONK.io, you can collide with other players by force and they'll fly right away.

I have never tried this in the past, so I can't say much. "Server-sided" UI itself is quite difficult to get working with precision, which can only be done through events as Dsioul said. There are a few games I have seen on Roblox like a flappy bird clone that was made with UI and supported multiplayer. I'm not sure whether they took a path other than events but you could try with events first and then try to slim down on bandwidth as much as you can perhaps?
