A lot has changed in the last 5 years or so especially with USB-C tools. Check out the TS-80P soldering iron (https://www.adafruit.com/product/4244) and a USB-C variable power supply (lots of simple DIY designs, https://hackaday.com/2021/07/18/its-super-easy-to-build-your... ). Those plus a USB logic probe or oscilloscope depending on your needs, and a nice USB programmer/debugger like the Black Magic or a clone of it is a pretty nice and compact setup ( assuming you have a laptop too). You can even power most tools from a good USB-C power bank.
