I cannot get out of ESP-01. I have dozens from Alibaba for 1€, and all problems are solvable with external CMOS components, which work quite well on 3V logic levels.
Depends on what you do. Few years ago I played around with micropython on a ESP8266. There a bit of extra RAM would have been helpful. As said years ago, can very well be that micropython is better optimized nowadays and it's less of an issue.
Biggest issue I can think of is trying to do PWM _and_ WiFi work simultaneously on an esp8266. If you have, say, an esp8266 serving up a small webpage for control and don't want to add an external PWM board then you might notice intermittent issues. This is more obvious if you're controlling something like a lighting ballast that's PWM controlled.
Of course now that I'm looking around I see https://github.com/khoih-prog/ESP8266_PWM which seems promising (subdivides the second of two available hardware timers to allow PWM that isn't sensitive to other running code). So there's multiple workarounds (libraries, breakout boards) besides upgrading to an esp32.
Also my favourite. I have one with a few sensors attached that has been running for months. It runs Tasmota and feeds the data into Home Assistant via MQTT.
Have you tried esphome? I never really got into tasmota because esphome was closely integrated with home assistant. Now it is part of the same project and integration is even tighter.
Not yet. But I really like Tasmota. The documentation is also good, the ESP32 port has an embedded language on it that one can use to extend its functionality.

I bought 50 from AliExpress a few years back for a couple bucks each.
