Tablet recommendation for handwritting notes

Kaixo!

So I'm a basque language teacher, who also does correct official language proficiency tests. The thing is that for my job I need to correct a lot of writings and other materials, and in order to avoid using that much paper and, of course, make my work more comfortable, I was thinking about buying a tablet. To be honest, I've never had one, since I'm a computer person, and even though I'm pretty tech enthusiastic, I haven't been checking the tablet market at all. So i thought asking here for some piece of advice, in case some of you have any recommendation based on your experience in similar uses.

As I've said, I'd like to use it to handwrite over documents, so I don't think I really need a very powerful tablet, but I really don't know if I will use it that much for other purposes, as I'm pretty used to use my computer and my mobile phone. Also, I try to use FOSS as much as possible, and I've been trying to avoid big tech companies like Google or Apple, for sake of privacy, internet democratization, and data sovereignty, among others reasons (I don't even know if those last two are used concepts in English, but they're rough translations from basque lol). So it's important for me to be able to degoogle Android in my tablet, or to have any other option like Linux.

Thank you in advance!
