you don't want peer to peer networking because it makes streamers paranoid about leaking the IP address (even if it's not actually a big deal, but it still gives the general geographic location if they don't have a VPN which could potentially be a few dozen kilometers off).
steamworks networking has a thing that hides the IP address (through servers) but I don't actually know.
unreal has networking through replication graphs, but blueprints seem to be very painful, and I think replication graphs are still a very low level approach that still requires you to solve a lot of issues on your own.
unity probably has (paid) plugins that would make networking a solved issue (but your game will probably look and feel the same as the example tutorial they offer).
godot has a better license, but I don't know how good the networking / plugins are.
from scratch is hell and you will never finish the game and you probably wont finish it even if you used an engine.
>>>/vg/agdg/ is probably the correct place to ask but I don't know how active it is.
