I usually buy used enterprise gear, and have been in a similar situation: switch ports are (relatively) cheap, anything that needs an actual CPU to do routing is spendy.

I've gone to Mikrotik for routing 10Gb in the home now. Excuse the horrible part number: the CCR2004-16G-2S+PC has worked out great for me. They're a bit hard to find right now, but I wouldn't hesitate to recommend them over whatever Ubiquiti is trying to sell in the space. For multi-gig routing, the Mikrotik RB5009 has also been a great piece of hardware.

25Gb is really getting into a different class of hardware entirely. If I needed to route at that speed, I'd seriously consider a Supermicro + Opnsense build.
