For what it’s worth, the original ESP32 is actually 5V tolerant, semi-officially acknowledged by Espressif. Good enough for hobby projects, anyway

I'm surprised cheap level shifters with the same pin pitch as various dev boards aren't common.
There's DIP-packaged level shifters that are 0.1"
Do you know where you can get one?
Be a little careful on those. It depends on what you're doing. Some of them are not suited to be used with the high data rates for I2C, or I2C only at 100khz. I found out the hard way with some of the SparkFun level shifters, years back.
You need to do a little research. It will usually tell in the spec sheet. Which is why the Arduino is useful. You don't have to buy a level shifter. You don't have to read a level shifter spec sheet.
And a lot of dev boards you will use as a hobbyist even include level shifters on the board, so you will have a 5V pin.
