I don't have any direct experience with these, but from what I do know, you should probably lean towards a harness that has exchangeable extensions to both save money and reduce clutter. Beyond making sure to use a lot of lube, start out on the thinner side, and then increase girth slowly down the road as you like.
If you're new to it, it's often a good idea to get a decent beginner's kit to test the waters... This one seems to have pretty decent reviews: https://tinyurl.com/yd6gdhcm
