To see what cycling can do you might want to have a look at
THIS blog by a former CC'er who started his journey at 38 stone

. Granted he started on MTB's but never the less, bikes are stronger than you think.
I can't remember when I was last 18 stone, sadly I've spent most of my adult life above that weight, but, I have a road bike and have had for years. I've also had carbon fibre framed bikes too and never had an issue. Oh I snapped a spoke once, but they'd done a lot of miles by that stage anyway.
Some manufacturers offer lifetime frame warranties, some don't, but generally speaking it's not the frames but the components that are most susceptible to strain, seem obvious right? I used to ride lightweight wheels with a low spoke count, but after the snapped spoke episode I decided to move over to high spoke count wheels. I prefer the knowledge that my wheels are pretty much bombproof these days. Stick to 32 or 36 spoke wheels, I use Halo Aerorage wheels, and you'll be fine, a lot of people recommend handbuilt wheels, but I've never had the time to wait for them, and also never had a problem with factory built wheels either.
Also I was advised years ago to avoid carbon fibre handlebars and stems, maybe sage advice, maybe not, but I've never felt the need to spurge ££££'s on fancy bars anyway.
My current road bike has an alu frame with carbon fork and steerer. My MTB is steel framed.
So in answer to your question, no, IMO there's no bike in particular you should be looking at. Have a look at the different manufacturers, sites like
Leisure Lakes,
Evans,
Chain Reaction etc will allow you to see many different bikes on one site, or if you've anything in mind go straight to the manufacturers website to view them.
At the end of the day there is no substitute for throwing your leg over a prospective purchase. So when shops are back open get along to your LBS, they are generally a friendly bunch and happy to advise and let you you try bikes for size, many will even let you test ride.
When you've picked something you fancy make sure it's available in a colour you like, because if you don't like it, even if it's the deal of the decade, the chances are you won't ride it.
Lastly, it's always nice getting a brand new anything, and a bike is no exception to this, but, you'll get more bang for your buck if you buy second hand, however it's imperative you know what your looking at, or take someone with you who does. There are a hell of a lot of very nice bikes festering in garages and sheds all over the country, but there's also a lot of worn out dross, and of course the scumbags selling stolen bikes as well, so keep your wits about you if you decide to buy used.
