Hi Emanuele @lost_into_the_world and welcome to GADC.
A lot depends on what you want to get from your drone, and since the regs changed last year a lot also now depends on where you want to fly.
Run a few of your intended flight scenarios through Good 2 Go, it might answer the question for you:
As for the DJI Mini 3 there hasn’t been so much as a whisper of a leak, much less any evidence of one being on the horizon. It’s a safe bet they will make a Mini 3 but it’s going to be three-to-six months away yet, and that’s before you factor in the global chip shortage issues.
There is also the sub 250g Autel Nano to consider too, this is due to start shipping next month.
