Been through this on my commuter
Tubeless works great on the commute until it dosent work, worst ones are a tyre slash or a large hole that a plug wont fix, sealant everywhere including over my clothes, then i had to fit a tube with a piece of cardboard covering the slash which meant getting even more covered in sealant by the side of the road in the dark faffing around with tyre levers slippery hands and tight tyres, once back home i then had to strip it all down and get messy again, fix the tyre with a mushroom plug, add more sealant, then clean up the bike and my clothes
I now just run Schwalbe Durano Plus 28mm tyres (just below Marathons in the puncture protection scale) with tubes, ive had less punctures than i had with tubeless and worst case if i do get a puncture its easy and clean to fit a new tube
Durano plus tyres weigh 480 grams, tube 100 gram so thats 580 grams per wheel, where as tubeless was 350 gram tyres, tubeless valve 15 grams, sealant 60 grams, so thats 425 grams in total, so the tyre and tube set up is 150 grams heavier but a lot less messier
