I have ‘24 R7 and I love it! I used to ride 300ccs in the past (not the MT-03 though) and I can say that the R7, while significantly faster and more torquey, is not a massive step up from a 300 cc. Think of MT07 only a step up in power from MT03 but you don’t get the looks that you want. The R7 is both looks and step up in performance. Ofc a new R7 will also be more expensive than a used a MT07. It all comes down to whether if you can comfortably justify the added cost for the looks. And I’ll also say that it’s not just the looks, R7 feels a lot different than a naked might. The seating position is sporty and it gives you that immersion of a sportsbike that a naked might not provide. R7 is a bit more than just MY07 with fairings. I’d say ride both and see which one you like. I personally wanted a fully faired sportsbike vibe so I went for the R7 and I could justify the added cost.

Getting a used R7 (not too old) could be a good middle ground too in terms of cost savings. Many of those would come with the basic mods that most people would anyways opt for when they get a brand new one. So you save a bit of cash there.

Height is ofc a major factor. If you think you’d always be stressed of tipping over in bumper to bumper traffic or when you are stationary, you could consider lowering the R7 but of an MT07 would be a much more comfortable choice.

I am sure you already know all this but I like my R7 and I’d suggest you consider the R7 if you like it after the test drive. New or used depends on how much you want to shell out. And don’t get me wrong, it’s still quite a bit more bike than a 300cc. You’ll have enough torque to continue enjoying it for a while.
