Tubeless is pretty easy if you don’t swap tires a lot. Remove the valve core and check the sealant level (dipstick an old spoke) every 6 months. Add some if under 4-5mm. Punctures generally seal themselves while riding although you might need to add air. Riders sometimes stop which does not help the sealing - just ride. Large tears (+5mm) might need a bacon strip or better yet a Stan’s Dart but they rarely happen. Putting a tube in isn’t any harder than a regular tire except you need to unscrew the valve stem nut and remove the valve. Always finger tighten only for easy removal.
