Congratulations on your Bolt EV! I just saw my first EUV on the road yesterday!
It is always good to have your Bolt EV plugged into the charger, so that it can be monitored and do reconditioning if necessary.
The question is whether or not to limit the charging to 100%? And that has been the debate.
With my 2017 Bolt EV, the choice was either 100% or 90% or lower and I did not like losing 10% of my capacity, so for its two years and 9 months of use, I always charged it to 100%.
With my 2019 Bolt EV, I can now reduce charging to 93% and I use this option, set only for "home charging" (the Bolt EV knows when I am home, charging by GPS) for a specific reason.
I started driving Uber full time and I really, really enjoy "one-pedal driving."
When charged to 100% the regenerative braking will not come into play, and hence I would lose my ability to one-pedal drive for the first hour or so of my Uber shift.
At 93%, I can one-pedal drive right from the start of my drive (and yes, I always drive in L and use the steering wheel paddle as necessary).
Then the Pandemic hit and I stopped driving Uber in late February 2020, but I still only charge (at home) to 93%.
120 volt charging is fine for your mileage needs: I used 120 v for my original Chevy Volt 1.0 and then as I started to drive my 2017 Bolt EV.
But as my driving for Uber increased, 120 v was just not good enough.
I had purchased a "plug-in" Clipper Creek 220 v 20 Amp L2 charger, but could not justify the cost to put 220 v in my garage for the Volt.
I then had a 220v outlet put in my garage for my 2017 Bolt EV and just love L2 charging with this Clipper Creek ever since!
