I've been a road rider for over 30 years. I crashed 3 years ago and totalled my custom road bike frame. After a couple of years I got the used Trek hybrid and I've been riding it for a couple of years. I think you can't go wrong with a Trek. Also some of the brands that you buy at REI are good. If you go to a big REI store, or a good bike shop, they will have brands that you can trust. For a reasonable bike that you can have faith in and that will last you a long time, you will need to spend maybe around $700 minimum for a new bike. Used bikes can be a lot less but you have to find one that is the type and model that you want, AND the right size for you.
I just got a new "parade" bike recently- a Schwinn Paramount from the 1980's. Actually I bought the frame used and added all of the components from my old bike.
you must be tall!!! that head tube is gigantic!!!
To the OP, Check out what is available at your local bike shops. Get models/names then hit the interwebs for customer reviews.
You can save a ton of money by purchasing 2nd hand, but you need to know what to look for/look out for. Not a deal if you save $400, but need to spend that on hubs, other bearings, and tune up. I know that number is extreme, but it isn't out of the question. I co-worker of mine had a very nice 80s road bike that he spent $500 on getting going again. hubs were shot, so he needed new hubs and wheels built. The shop was able to find OG hubs for him, but they were 'spensive! If you are buying a fairly recent bike, it will not be hard to find replacement hubs. Best to not need replacement parts out of the gate though.
You should also be weary of brands owned by off-shore conglomerates. Schwinn had a great reputation in the 80s and 90s, but were scooped up by Chinese ownership and now is a mass produced turd. I'm not 100% sure about GT, but I thought they suffered the same fate. Mongoose, Diamond Back, and other big names from the 80s suffered this fate as well.
Really hard to go wrong with Trek, Specialized, or some other big brands, but check out some lesser known brands like Felt. Surly is a great company, but they have a cool factor that costs extra. If you have a Performance bike shop, their Scatante (spelling is probably wrong here) is decent. Fuji can often be found with better parts than other makers for the same or less. Watch out thought, they sometimes scrimp on brakes or cranks.
Most important thing to do is find out what size you need. Buying the wrong bike will be money wasted. I had a friend who raced triathlons and thought he knew about fit. Yet a shop owner convinced him that the bike he had in stock was his size. It didn't feel right on the test ride, and after a few hundred miles, it still didn't feel right. He realized that the guy lied and sold him the wrong size bike because he didn't want a sale to get away.
There are so many options out there that you really need to provide a narrowed down description of what you want to spend.
