Default Ale - Warm or cold conditioning best? Full or no psi while conditioning?

(Let’s go with a specific example – say a Celebration Ale Clone - 5gal - all-grain. Make all the assumptions needed.)

7 days in primary
Dry hop
7 more days in primary
Rack to keg
“Condition” 3 weeks
Force carbonate (in refrigerator) for 3 days to ~2.6 v/v

I think full attenuation is pretty much achieved after 14 days, right? - given a “quick” yeast and standard practice. But on the micro/absolute level isn’t attenuation actually a “long-tail” thing, that has “some” micro affect for the entire three weeks? Maybe not. Hence the following questions:

1.) Would there be any noticeable (or even theoretical) differences in taste if the ale was matured in the refrigerator for the three weeks (35 degrees) vs. in the brew room (70 degrees)? (Wouldn’t it just take slightly longer in the cooler temp?)

2.) Would there be any noticeable (or even theoretical) differences in taste if the ale was force carbonated immediately and held constant for the three weeks, say at ~2.6 v/v? (Would any maturation processes vary with pressure? If so is this also temperature dependent?)

3.) Finally, wouldn’t it be more technically correct to say (given the uppermost example) that we’re not “conditioning” the beer for 3 weeks, we’re “maturing” the beer for 3 weeks? We’re “conditioning” the beer in that upper most example for exactly 3 days. (It’s kind of a pedantic-ass call, but nevertheless isn’t it true?)

Ales traditionally condition a cellar temps, right?, which is probably somewhere between the temperature examples given. I wonder which way (cold or room temp) is better for the TASTE of said example.

No worries; just curious - a kind of thought experiment. Any info or clarifications are appreciated.

The beer will mature faster the higher the conditioning temperature. On your second point Im not totally sure I got to carb after fermentation but I have a good pipeline build up so I like the extended conditioning time to let me get to bottling (I'm a sucker I keg THEN bottle). For the third point I use the 2 terms interchangeably for the most part though generally i consider warm temperatures to be maturation and cold temperatures to be conditioning.
Celler temperature is mid 50's to low 60's. Cold hurts the taste of beer I think somewhere in the mid 50 is ideal (for me ymmv)

I'd age the beer in the brew room for 3 weeks. When you put the beer in the fridge you drop the yeast out of suspension and they go dormant. Aging at room temp will allow the yeast to continue "cleaning" up the beer. Refrigerating will slow that down dramatically.
