Don't know Apple, but Androids can be put into Bootloader and Recovery without password or pin. Most Recovery[s] give you access to the file system (if not, Bootloader can be used to install your own Recovery). Extract the files and run through whatever software you have for decryption.

Can you name a single Android phone or tablet model that is <10 y.o. for which you can access personal data with this method?

Nexus 6 (late 2014), as well as rare Nexus 5X (2015), where owner enabled "OEM unlock" option.

Obscure Chinese brands made such android phones for few more years.

All Google Pixels (2016 and later), and virtually any android phone made after circa 2018 are safe from naive bootloader attack: user data is encrypted, plus you have to "OEM unlock" to even get the recovery to run.

My mistake. Most of my Android devices are unlocked.
