Should I upgrade my pocket camera to full frame for 3 week photography trip?

I’m currently shooting with a little Sony RX100 VII and considering a Sony ACii with Sigma 28-70 or Sony a67000 with sigma 18-50 for a 3 week trip to Japan. The whole trip is devoted to photography and hopefully capturing some good compositions and moments. Here are some recent shots of street, beach, and everyday stuff around LA. Based off these photos do y’all feel like it would be advantages to upgrade for low light neon lights capabilities, ease of use, creative opportunities with more features and a f2.8 lens? Will my RX100 VII be able to handle the night life of Tokyo? Is traveling with a pocket camera actually a better experience than a full frame/apsc setup? I’ve been considering an upgrade for over 6 months but haven’t pulled the trigger because I don’t know if I really need it. Hopefully y’all have some advice for me I’d really appreciate it!
