Depends on the road surfaces you’ll be riding on. I think the biggest benefit of tubeless on a road bike is to prevent against pinch flats, as there’s no longer any tube to get pinched. So if you ride on roads with any sections of poor surface, or if you plan to do any gravel sections, then tubeless is worth it I think.
If riding on nice pristine surface, then I don’t think there’s really much benefit to tubeless - as I’ve read reports of people saying tubeless doesn’t do so well at, say, sealing a nail hold due to the high pressures involved in road tires. (FWIW, since switching my road bike to tubeless over a year ago, I’ve not flatted on either road or gravel. It’s possible the sealant has sealed up some small puncture holes, but I don’t know - have not seen any evidence of that. The primary protection I’m looking for is prevention against pinch flats)
Some might say weight savings, and eliminating friction between tire and tube, but I don’t think these are big enough to justify the work to get your tubeless setup dialed in.
