For battery degradation, there's a great thread [1] in the Model 3: Battery & Charging sub-forum. Having read through the whole thread, I can say the entire thread was quite interesting, in particular the posts from AAKEE.Good point. Gas prices are still pushing people towards electrics. Existing orders won't be affected by the price increase, of course, and only those who are at the limit of their budget would walk away due to rate hikes. I don't expect delivery times to be affected for quite a while. If only Tesla was ramping up Model 3 production the way they're working on Model Y production.
I've read accounts that it can hit the battery hard. As in 8% over the course of a hot day. If you charge each night that's not a significant problem for range for most commuters, but it's a lot of battery use through the warm months. Not that these batteries seem to have a longevity problem. After 100,000 miles, they only seem to degrade about 11% - even with heavy fast charger use.
Edit: Another account claimed only 12 miles lost (~3%). It may just be a difference in ambient temperatures. Fire it up and find out how it works for your situation.
It all boils down to battery degradation has two main parts: (1) cycle aging and (2) calendar aging. It appears that, for most people, the cycle aging is essentially a non-issue and that most degradation is coming from a high state of charge and heat. Most people lose the most capacity in year 1, and then the calendar aging levels off.
If you're following the standard Tesla recommendation (charge to 80%), you're in good shape (and will be covered by the battery warranty that guarantees 70% or higher battery capacity after 8 years or 120k miles). If you want to try to optimize for even better battery life, the referenced thread is a good read.
For the particular question about running overheat protection as a mechanism for preserving battery life, it appeared that people thought that was an expensive way to try to get some minimal benefit -- they recommended to try to park in shade as potentially being more beneficial for less cost.
