I would be careful with thinking that iOS and iPadOS have much in common with FreeBSD or that Android has much in common with Linux. For example: The file systems supported by iOS or iPadOS are a limited selection of Apple and Microsoft file systems, there's no compatibility with UFS or ZFS. I don't know if iOS allows to access external drives at all, at least iPadOS does. Linux has got amazing real-time capabilities, Android has got no real-time capabilities at all. They are very, very restricted operating systems, not just for the end-user, also for software developers. Even if they should provide something you consider as very good from FreeBSD or Linux, from one day to another they could deny usage, see http://crudebyte.com/jack-ios/ios7/ . You cannot access or backup iOS or iPadOS devices by a FLOSS operating systems. They could become temporarily inaccessible by FLOSS solutions, see https://github.com/libimobiledevice/libimobiledevice/issues/828 and if the FLOSS solution should work, be prepared that you could damage data by using it, without making a user error. Even by using Appel's iTunes software, what is called a complete backup actually is an incomplete backup. Some data that is important for the user is only available on the device, there's no way to use file sharing, send it by email etc. or to restore it from a backup. Some other data can only be restored from a backup, so there's no way to share it. Some data can be shared, but it could become very complicated. This has got nothing to do with FreeBSD, a few lines of FreeBSD code aren't nice, if some of your intellectual property is captured. FWIW I'm using iPadOS as an audio DAW and for drawing. However, I'm also using a mobile FreeBSD, https://www.nomadbsd.org/ , it's mobile, just without a device to run it. A desktop PC or laptop with an USB port is needed to run it.
