I used to run a vape review YouTube channel here in the UK for a number of years, and generally the advice I've given is to find a reputable vape shop and go in and ask their advice. As long as they don't give you a product that means you're rebuilding coils and such then they should be able to offer a number of options for you.
Vaping stopped me smoking and is no-where near as bad as combustible cigarettes, and things like 'popcorn lung' are vastly overblown by the media - mainly due to it coming from workers in a popcorn manufacturing plant where they inhaled diacetyl consistently, although the law suit eventually failed when the workers sued the company due to lack of evidence.
Where vaping is involved the biggest concern was the use of diacetyl in some flavourings, however, this was vastly overblown but still manufacturers changed habits using less of the stuff to sweeten their flavourings.
I could go on about this all day, but I made this video some years ago that may answer some questions -
If you're going to switch from tobacco to vaping though, I would absolutely suggest finding a flavour that is not trying to replicate tobacco and is enjoyable in it's own right, that way it removes the desire to spark up by giving you a different flavour to enjoy rather than reminisce on the old smokes.
Also if you've not smoked for a bit, go into it with 0% nicotine as it likely won't be need because you're replicating the motions rather than weening off the nic. Funnily enough, the highly aggressive component of cigarettes that addicts you is the chemicals added in, and not the nicotine on it's own.
Over the years I've gone through a lot of the media rampage posts about the dangers of vaping, and pretty much all of them have been proven wrong, false studies, or outright debunked.
This is an interesting read from Kings College -
