You can run a VPN like wire guard, ad blockers such as Adguard Home or pihole or even media servers on your openwrt router.
It's a joy to use on x86 hardware though. You can run as many services as you want.
Best thing to do is to get a fanless mini PC with multiple ethernet ports and hook up a decent access point to one of those ports.
Yes I do. I have hooked up my x86 openwrt router to my fiber modem.
Nowadays you can easily run it on a single board computer like the raspberry pi or any x86 mini pcs. You just need to hook up an access point for Wi-Fi which doesn't need to be able to run openwrt.
That's exactly what I do. You can keep your ISP router and hook up your openwrt router to one of its lan ports and have two wifi networks.
I only know one company that sells routers with openwrt pre-installed. It's called Gl-inet.
You can run it on a raspberry pi or an x86 mini pc.
Not sure how unusual it is but I run openwrt x86 on a fanless Asus mini PC as my main router at home.

My laptop has Intel UHD graphics. Things are slightly better since I enabled TLP.
