I just bought two bottle holders from French
Zéfal and installed them. I noticed when you do
not have a bottle in them, the plastic arms are
too close so they hit each other and make an
annoying sound. But just cutting off a small
part of one of the arms and it is fine.
The bottles are also from Zéfal. 650ml, BPA
free. Seems good.

That 2 - 3 hours is for a bottle that has been opened. Once the bottle
is opened bacteria begin to grow in it. That's why it says 2 to 3
hours. However many bicyclists drink water (usually municipal tap
water) that they've filled their water bottles with. That water has a
longer life because of the stuff the municipality puts into water to
purify it for human consumption.
Btw, cutting the lips off of your bottle holders may cause them to not
grip the bottles as securely as needed to keep the bottles from being
ejected from the holder on rough surfaces or panic stops. this is more
likely to happen with 750ml bottles than with 500ml bottles.

Two to 3 hours seems overly cautious to me. Pure water is *very* poor in
nutrients. Whatever might grow after being fed with the bit of your spit
that makes it into the bottle can be already growing in your mouth.
Given enough time (weeks or months), some mold might grow, and to
prevent this I wash out the bottles with dish soap and hot water after use.
The municipal water supply where I live (Zurich, Switzerland) isn't
chlorinated, so I wouldn't expect any difference between that and
bottled water. Near the mountains there are lots of high-altitude summer
pastures ("Alp" in Swiss German) with a fountain fed by a spring. I
often refill water bottles from these.
I always use anodized aluminum bottles like this one:

I switched to these back when plastic bottles always gave the water an
unpleasant taste, although that might not be a problem nowadays.
I use a plastic drinking bottle, one or two stainless thermoses plus in
summer several re-filled PET bottles (the cheap "disposable" ones). On
long MTB rides easily five liters. Even after non-chlorinated water has
been in any of those for a whole day I never had anything taste funky.
We strip the chlorine out via a filter in the kitchen drinking fountain.
