This Felt Versa does look like a good buy. It's tyres on the wider side for some comfort and a triple chainset will mean good gear range.
The only thing I would say is that it's geometery is not the most relaxed available. Neither is it the most aggressive, but it is a fitness bike so assuming you are all in proportion, you will be leaning forward a bit.
That's probably okay, if you start out with a couple of very short trips and slowly build your mileage up.
A bike with more relaxed geometry - so a more upright seating position - will probably be more comfortable for you in the short-term but it might hold you back a little bit as you get back some core strength and flexibility. Reducing the handle bar stem length might help shortern the reach but at the expense of making the steering a bit livelier which might be something you don't want. It also wouldn't address the position of the pedals relative to the saddle (seat tube angle) and there might be a limit on how far you can rotate your hips. That said, if the shorter stem helps you enough in the short-term, you would always be able to flip it back to the original step once you get used to being on a bike again.
You really need to try a bike like this and one with more relaxed geometry (shorter effective reach) and see which you think will suit you best. It is very hard to say, without seeing what your flexibility is like, whether or not the Felt Versa will suit you. It will be fine for most riders though and so long as you take it easy it will probably be okay for you.
Edit: I don't know whether there is a staggered (low sloping top tube) flavour of this bike, or whether the one you are considering has the low sloping top tube, but if your flexibility is that poor, you might be better of with either a staggered or an open frame that's easier to get your leg over.
Again, I really encourage you, if at all possible, to try the bike. If you are comfortable on it, in terms of reach and position, go for it.
