Good cameras for nature shots

I’m using a very basic smartphone (Motorola G8 power) and while this often serves me fine it also leads to lots of frustration, both in the capturing and uploading stage. I’d love to upgrade to a proper camera but it’s not in the budget right now. It’s mostly an issue for macro and telephotos, which has had an impact on which species I focus on (generally medium-sized and more static beings such as plants and fungi). I see this is a positive side-effect, but will order some lens attachments this week to expand my options and increase the quality of my photos.
