I suppose I fall into the "experienced player" category and through that I've helped
HoneyGames with a number of bugs that you'd expect to see in such a complicated game as this - so this is my take
At the bottom of this (long-winded) post you'll see my take on the girls of NCC, who they are in a relationship with (or will fall back to if you don't pay them attention) and the other girls who can affect their story. A lot of stories overlap - so you can have a general save with no focus and re-direct this to different saves as girls become available or not.
For example, Roberta (who's a potential exclusive sex partner) does't appear until later so you could start a save with Luana/Michelle/Rebecca involved, add Yanmei into the mix on Day 35 and then Roberta on Day 41. She's good friends with Vanessa so best to keep in her good books too and you may want to use that fact to pursue Vanessa too.
As a rule of thumb I tend to keep Luana and Yanmei around as fuck buddies (unless pursuing Ashley/Yvette), tend to favour good relationships with Michelle & Rebecca and keep in the good books with Adele & Riley. If focusing on any of these change the way you handle them.
I've already posted the current saves I have in the game here (
https://f95zone.to/threads/new-coral-city-v1-0-honeygames.28118/page-100#post-3337124) but split the Elsa one to include Catherine or not because I wasn't sure if sex with her would help or not - being Leonard's mom.
There are many ways of playing the game and it's really a case of trial and error - I've restarted multiple paths over again! If you really want to know the impact of your choices use Notepad++ or something similar and dive down into the *.rpy file, looking for variables, searching multiple files with terms like "good +=" and "tatiannaconnor -=" for instance. Someone writing a walkthrough would likely have to do this anyway - and write a small book in the process. It depends if you want to see as much of the content as possible or just try different options.

NOTE: As
HoneyGames has previously mentioned, if you want Adele to split with Gary choose any of the plans when offered - but if you want both Adele & Lara to leave Gary choose the Catherine plan (you need to have had sex with her)
