I think I know some music theory and I have no idea what Mike meant.
In your chart, I would only suggest that you need to be consistent with flats and sharps and use the enharmonic spellings. This may well lead to E# instead of F, for example, or even a double flat etc.
The way I learned it, to spell a triad, you always skip a letter. So it’s either C# E# G# , or perhaps better, Db F Ab
Thanks for the input Matt.
If
you have no idea what Mike meant, imagine where I am on his comment

Your input on the enharmonic spellings is the kind of value-added feedback I was hoping to recieve. It sounds like there is nothing
structurally wrong with my table, which is good confirmation for someone like me who is just learning this stuff. So I will ignore Mike's "No" and replace it with a "Yes". But enharmonically/symbolically there are some issues; got it.
Brain 1 says "Fix those enharmonic issues because it will pay dividends later"
Brain 2 says "No problem dude, when you pick up your bass and jam, all is well if you can find those notes on the fretboard"
Maybe (for me) the best table would have both enharmonically correct symbology and "simple" symbology (no E#, Cb, ##, etc.)
Based on your input, Eddie's table with Dan's correction and my table are both enharmonically wrong because both have simple symbology. Can you point me to an enharmonically correct table?
I also notice that Eddie made a neat connection to the circle of fifths that might bring further insights if I do some drilling.
Here is my table again for easy reference.
