I would love to meet people in person again! But as you said, travel planning is more challenging than it used to be. My plan is to be in Porto, Portugal the whole month of September. So if it's there or easily reachable from there, I would do my best to join!
Another option would be Bansko, Bulgaria (for cost saving). I'm not sure if you've ever looked into that. There's a big digital nomad community there and the weather will still be amazing in September, for hiking, etc. This is where my current base is when I'm not travelling. I'll be back there in June/July for https://www.banskonomadfest.com/ so could give you a tour in case you wanna come and check it out :)
