Umm.. there are literally 100s of small Android phones:

Set the size slider to max 5 (6 is not small), set the date slider to min 2020 and there's.. One. From a manufacturer I've never heard of.

There actually are more than one (gsmarena is better for this search), but not many and as far as I can tell none with wide availability or much hope of getting security updates etc far into the future. The best option at the moment seems to be ebaying an old phone that's supported by Lineage and hoping it doesn't die.
