If you mean properly signed certificates (as opposed to self-signed) you’ll need a domain name, and you’ll need your LAN DNS server to resolve a made-up subdomain like lan.domain.com. With that you can get a wildcard Let’s Encrypt certificate for *.lan.domain.com and all your https://whatever.lan.domain.com URLs will work normally in any browser (for as long as you’re on the LAN).
Right, main point of my comment is that .internal is harder to use that it immediately sounds. I don’t even know how to install a new CA root into Android Firefox. Maybe there is a way to do it, but it is pretty limited compared to the desktop version.
You can’t install a root CA in Firefox for android.
You have to install the cert in android and set Firefox to use the android truststore.
You have to go in Firefox settings>about Firefox and tap the Firefox logo for a few times.
You then have a hidden menu where you can set Firefox to not use its internal trust store.
You then have to live with a permanent warning in androids quick setting that your traffic might be captured because of the root ca you installed.

It does work, but it sucks.
