Unless you're willing to do the messy work yourself, or pay to have a shop to it for you, you'd be better off going with tubes and a more puncture resistant tire than the Conti GP 5000.
I have GP 5000s on my road bike (with sealant) and I like them, but I don't mind spending the time to add sealant every 3/4 months and taking the tires off, and replacing the old sealant with new every year.
Personally, I wouldn't run GP5000s with tubes because I'd be afraid of punctures. There are a number of more puncture resistant tires on the market that are only slightly slower.
Side note: a couple of weeks ago I had a puncture on my back tire while on a long ride. Lots of sealant flying everywhere, but the sealant eventually sealed the hole and I was able to complete the ride.
I do carry plugs and an mini electric pump, but luckily I didn't have to use them on this ride.
When I got home I added some more sealant, because I had lost quite a bit when the tire was punctured-good as new.
