In days past some drive vendors had different sector layouts for drives and would cause issues with raid. Pretty sure most nowadays are all the same layout and you won’t run into any issues. I still look to get the same drive model anyways just to be perfectly sure that there are no issues.
Even then you may run into weird issues like one of my 1.2 TB enterprise ssd drives was reporting 1.12 TiB rather than 1.09 TiB the other 7 drives had. TrueNas refused to build a vdev with that drive and I had to return it to get a new one.
Pretty sure there’s not a per-domain setting for that. If you have HTTPS-Only Mode turned on in the settings it will always try to use HTTPS first and present a warning before switching to HTTP.
If you want to continue using HTTPS you can setup your own CA certificate to sign certificates for your .LAN domain names. All you need to do then is add the CA certificate to your trusted certificates in Firefox and the signed certificate to the device hosting the HTTPS service.
EDIT: TIL there an exclusion feature. Neat. I didn’t see this on Firefox for Android though. https://support.mozilla.org/en-US/kb/https-only-prefs
