@GarethMcCaughan thanks for all the tips, I'll definitely have a go at some daily ones and will follow/attempt the CCCC ones in here as well
I have to say a really huge thank you to @OmegaKrypton, who spent over 1.5 hours with me, slowly walking me through one of his (already solved) puzzles on PSE. He gave me the chance to think aloud and nudged me in the right direction, adding notes similar to what you mentioned (like abbreviations) and by the time I had solved the first 8 (with guidance), I managed to knock out the remaining ones on my own (albeit being easier because I had letter clues).
