Upgrade beginner racket?

I’ve been playing tennis for a little less than a year now. I’m still a beginner, probably around a 2.0-2.5, I can comfortably hold a short rally but my serve still needs work.

I purchased an older Babolat Boost Aero for around $30 used when I started with the intention of upgrading if I stick with it. I think the racket is fine, I don’t love or hate it, but I really haven’t tried anything else. The head is 102 sq in, weight 9.2 oz. Is there any benefit to upgrading at this point? I have the option to demo rackets through a local store, but I don’t know if it’s worth spending money when I’m still a beginner. Unfortunately I just switched where I’m taking classes and don’t know the coaches well enough there yet to ask their opinion.
