I’m spoiled now. I prefer ubiquiti equipment for my network, security camera, and even door access.
However, if you prefer completely open source I can recommend opnsense and openwrt. Personally I prefer a single point of configuration… So all ubiquiti for me… It makes it easy to restore a complete network configuration as you are discovering is a pain.
Maybe start with the new cloud gateway max as a router if you are interested.

Well I use a fire stick with smartube and jellyfin. Works just fine for my needs. YMMV
