CPU Recommendations?

[XrayDoc88]

I've been running pfSense for many years on mini PCs.  I'm thinking about upgrading my two home networks to at least 2.5G, and probably 10G.  I think I'm also going to switch to OPNsense.  Both home networks are currently connected with an IPsec site-to-site VPN.  When I upgrade, I plan on switching to wireguard.  Each home network has multiple APs, a NAS and several PCs.  Both homes have 1G fiberoptic WAN connections.  I also plan on creating VLANs on both networks, which I currently  do not have.  I'd like to stay with mini PCs if possible.

What would you consider the minimum CPU to get?  Is the Alder Lake-N150 adequate?  Should I get better?  Thanks!

P.S. I wouldn't mind mini PC suggestions either.  I've looked at the "official" OPNsense options.  I currently have Qotom, but want 10G connections.
