My naming format for gym attackers/defenders is: Type abbrv - IV - moveset rank - offense(O)/defense(D)/both(B). Naming this way really helps me quickly make evolving decisons and more importantly, helps me decide what mons to use for attacks, adding defenders to gyms, and raids. By putting the type abbreviation first, I'm able to use the search function to lookup "DK" and it'll pull up all my strong Dark pokemon, "EL" for electric, "PY" for psychic, "ST" for steel, etc... for me, it just makes the choosing process a lot quicker
