Seeking advice for cascade thermal chamber - refrigerants and maintainability

My company is seeking to purchase a thermal test chamber such as this model from Test Equity with these specs with details such as using R-404A for the high stage and R-508B for the low stage.

My background is as an electrical engineer - I've summoned repair of some chambers by a refrigeration technician and learned a little bit through that, but I don't know refrigeration in any useful capacity.

From what I gather, R-404A's days are numbered due to its GWP. R-508B looks even worse by GWP, but perhaps there's less choice for very low temperatures. I'm not looking to save the planet through my choice of refrigerants - I just want to know that there's a supply of the original refrigerant or a suitable replacement that we could use if we ever get a leak or need to replace a compressor.

Besides refrigerant choice as a potential deciding factor, is there anything else I should look at in terms of easy servicing and longevity?

Thank you!
