Jossam is my favorite ship of Sam's of course, but honestly I really love all of her more known ships that she's been given over the years. I feel like too many people clown on Daring Duo (Sam x Mike), although I don't ship it much anymore it was pretty much my gateway to the Until Dawn fandom and shipping as a whole, so I have a big soft spot for it.
Chris x Sam is another I've seen around and although there isn't much of it I don't HATE it (they are fun and I love that cut dialogue of Sam's mom lmao).
Sam x Beth is probably her best lesbian ship imo. They're so well aligned morally and character-wise that I always forget that they don't share any actual lines lmao. But out of the women Sam and Beth feels the easiest to slot into canon for me.
I'm not big on Semily granted, but I get the appeal and respect it. I've seen nothing on Sam x Ashley, Sam x Jess, or Sam x Matt, but hey I'm sure there's some cool stuff out there for them.
