Cleared for Takeoff
I'd order any viewing supplies you need right now. Shortages will get worse as the event approaches.
I've used Baader solar filter films in 2017, and I plan on using Thousand Oaks Optical filters this time, just because of the warmer color they offer. Both are ND5, they work great for cameras and human eyes. Probably will have two cameras, each with one filter type. Decide after which one I like more.
If you have any doubts about the quality of your filters, take a couple photos through them with an older camera - if they let any significant amount of IR through, the image will look all purplish through it, instead of a more neutral/yellow color as it would appear with the naked eye. Places like Agena Astro sell both types, and a 12" square sheet is $30 - you can make filters for multiple lenses and a few pairs of eclipse glasses from all that. A couple from 2017:
