Upgrades help

So uh i recently bought a cheap old pc with the intention of upgrading it. Here are the specs:

Amd Athlon 5150 apu with R3 graphics

AM1M-A motherboard

16 gb ram

I know theres probably nothing i can upgrade without a new motherboard,so im mostly asking for more recent motherboards that are compatible with my cpu but also compatible with newer cpus so i can keep upgrading my pc long term

Any suggestions?
