Optimal OS for old (mid 2015) but good MacBook Pro ?

I have a MacBook Pro (Retina, 15-inch, Mid 2015) which I bought second hand a few years ago. It had been cleaned up and rebatteried by a guy who fixes and refurbs older macs - still fast and heaps of battery life. I don't do anything that I need it to be super speccy for. Mostly just web browsing, email, streaming tv/movies/music, working in basic adobe and office apps.


It's still running Mojave (10.14.6). Have avoided updating OS in case it slows it down, but now at the stage where some functions aren't working - e.g. airdrop doesn't 'see' this machine from my phone or from my newer work macbook


Official apple compatibility advice aside, wondering if updating to a newer OS (e.g. Monterey?) will compromise functionality or speed at all? If so, which OS beyond Mojave would be a safe bet while allowing devices to talk to each other and making the most of other handy functionality of newer systems?


Appreciate any advice as I'm not very knowledgeable about what this hardware can handle, and not confident I won't mess up a good machine. MAchine specs below.


Thanks in advance.
