As for the OP's typing experience, I was looking into softer-typing switches for somebody, recently.
In terms of linears, Gateron Pro and CAP Yellow are reasonably-weighted, bottom-out isn't hard, but isn't necessary. Same for Gateron Pink. Silenced linears, like Silent Alpaca and OUTEMU Silent Peach, can be even better in this respect. The OUTEMU silent tactiles (Lemon-Lime and Cream Yellow) are like that, and cheap to boot.
So one solution is trying not to bottom-out by experimenting with spring weights. Another is using dampened switches (which are common and cheap now, and take advantage of the travel provided by MX.)
A third option is trying to actuate at the top, leaving the downstroke mostly untouched. If you put a 63.5 - 65 G spring in a Kailh Pro Purple, for example, it's like a Brown that actuates at the top. You move on to the next switch before the switch is bottomed.
For the OP, the first thing I would have tried is just a low-profile Choc White keyboard. Like the OP, I don't necessarily find the giant-travel of often-scratchy ('chuffy') MX and Topre keyboards to be the highest form of typing. A well-designed low-travel switch can be just fine. It's too bad you can't just buy a TKL full of Choc Sunsets.
BTW I don't know what Choc Whites are like, but BOX Whites are excellent. In the hype for Jades and Navy, they are underrated. It's crisp, but light. Easy, long-form typing. The (correctly-implemented) MX Brown of BOX Clickies. I guess the Chocs might be 10 G heavier?
