The bike style most suitable for your use is a reasonable drop bar bike.
Some time ago, the only reasonable drop bar bikes one could find were cyclocross and touring bikes. If you made the mistake of purchasing a "road" bike thinking you ride on roads and thus a "road" bike is optimal, you'll find the frame is reduced to such light weight that it won't withstand anything more than 70 kg rider, or any road other than a perfectly smooth road. Furthermore, the "road" bike would have tire clearance for approximately 25mm tires which are arguably too thin, and the riding position would make it clear it is only useful for racing.
However, today a lot of reasonable drop bar bikes have appeared under the category of gravel bikes.
My advice is to compare many bikes from all of these categories (gravel, touring, cyclocross) and pick a choice most suitable for you. Pay especial attention to the ability to attach accessories and the riding position. You'll probably need fenders (unless you never ride on wet roads), pannier rack (unless you never carry any cargo), kickstand (for commuting), light (preferably hub dynamo powered; unless you never ride in the dark), bell, reflectors and lock (for commuting). You might also prefer to use a cyclocomputer. Some of these can be added to any bike, but for example a bike could lack fender and pannier rack mounts and some bikes are hard to fit a kickstand to.
As reasonable drop bar bikes don't have suspension but rather rely on the inherent suspension on the rider's arms and legs, sometimes you might hit a bump unprepared. Thus the frame and fork should be robust enough to take that bump. I would prefer frame and fork built from butted chromium molybdenum steel. Carbon fiber? Forget it! If you for example crash on a bike with carbon fiber frame or fork, the crash could damage the carbon fiber in an invisible way, and then the carbon fiber could fail "just riding along". Note that even aluminum is somewhat questionable material, because it has a finite fatigue life and is thus prone to cracking. Steel has an infinite fatigue life.
If you might ride in the rain, you might find disc brakes better than rim brakes. Fortunately, today most reasonable drop bar bikes are sold with disc brakes.
Then there's the question of what tires to use. If the main riding is commuting or other riding on regular roads, put 32mm Continental Grand Prix 5000 (or similar), but if the main riding is on fire roads and the commuting is only occasional, you might prefer wider tires. Which tires would be optimal then I don't know. You can at least find rolling resistance data from https://www.bicyclerollingresistance.com/ but I don't think you find a decent low rolling resistance tire wider than 32mm.
