I’m also a noob with tech anymore. My old faithful router started dropping this year, replaced it with the Flint 2 earlier this year because I also wanted OpenWRT. It comes with OpenWRT installed, but I don’t think it’s the plain old vanilla OpenWRT, so when I hooked it up and started setting it up, it needs a firmware update anyway, so I installed the actual OpenWRT from their site. It’s been great since, totally happy with it.
