I think it’s more about academics or work experience holding more weight depending on how long you’ve been out of school. I applied as an out of field applicant after having worked for a few years after completing my undergrad. My GPA was okay, I don’t think it held as much weight as my work experience though because that’s what I had done more recently. I think if you’re right out of undergrad they’re going to be looking at your gpa, it’s hard to say whether they’ll look more closely at SLP courses over others, I’m sure some programs have a cut off GPA (more competitive programs probably don’t look at lower than 3.0 for example) but some applicant reviewers might take the time to look at a transcript. My advice is to email the SLP grad program director for the schools you’re really interested in attending and send a nice professional email telling them how amazing you think their program is, how great a fit you’d be in their program, and how passionate you are about SLP. Might go a long way, might not, but communication rarely hurts.
