I love the provari (I own like 5 of them) and I have a couple of mods as well - I also quit vaping (although not for nearly as long as you) and went back to it.
A couple of things here, speaking from experience. After three years of not vaping your starting from scratch again, as far as having to readjust to vaping, most especially if you went back to smoking, even for a couple of months.
Your lungs are not going to be able to handle higher wattage vaping, you'll cough. That said, you might enjoy something that will give you a nice range, so that you can begin slowly, and move up as you readjust to vaping in general.
I would suggest either starting with a aspire zelos kit which comes with the nautilus 2 (although you will likely have to fill that tank once a day, perhaps twice on some days ) or you can get something such as the tesla nano 120, or the geekvape aegis, or perhaps the JAC which is quite popular among provari lovers, or the Pico 25 kit which comes with a lovely tank that would work nicely for you.
You don't need, and perhaps will never even desire, a mod that will do 200 watts. I use a 120 watt, two battery mod and the batteries last me 4 full days when I use nothing but that mod to vape. (I've done it so I do know). You can easily do a single battery 75 watt device and be perfectly happy.
Tanks that might work for you are the Melo 3, the Ello, The full size Nautilus, the Triton, etc.
I think I agree with Opinionated, the Zelos starter kit is a nice mod, and the N2 (though it has its quirks) is great MTL tank. As is the Melo II ,III, Triton, etc.
If you want to start sub0hming that is something you can do as WELL, but many folks who really prefer a sub0hm setup have a MTL setup for work or other stealth situations, as you can vape a higher nicotine liquid with that, and then save clouds and lower nicotine and higher VG liquid for situations where it's easy to make clouds. I think if you did start smoking, transitioning might be drying (and remember, vaping has changed some, so some of the MTL setups are more versatile and provide more vapor) so sometimes starting small can be an easier transition. Plus, you will have a backup if your gear breaks... Would hate to see you have to start over X3. By the way I have some provaris, but I got an aspire zelos 75 watt TC (you don't need that necessarily, they make a 50 watt non TC for cheaper) as my backup vape and I really enjoy the size, the vape quality, and the form factor. I use it enough that I'm not sure it's really a backup vape anymore, LOL.

You two are making interesting points.
The MTL and DTL aspect is probably what is most weird and confusing to me right now.
I guess back when I vaped everything was MTL?
I think I will head on over to a local vape shop on Monday before pulling the trigger on a setup.
I expect most shops have spare drip tips and let people try out setups before buying.
I will try both and see what suits me best.
Since mods do both and it is dependent on the coil resistance I will chose a tank to go with it after having tried both.
I do like the fact that the smok alien has 200 watts though as if I end up eventually wanting more power to do DL it will be able to. 75 watts might also be sufficient for DL vaping so the aspire zelos might be a good catch. They are about the same price.
If I end up wanting a MTL tank I will probably try the nautilus 2 as a few people have mentioned it already.
If I decide to go DTL I will probably pick up a OBS Engine or try the TFV8 if I go the smok route.
I will also pick up a Velocity V2 clone.
SO much to learn.. exciting times to be a vaper!
