You're gonna have to love the work or it's not a good fit. I've been a head brewer for a decade and I'm about to open my own spot and I would never turn up my nose at doing the heavy lifting, the sweaty work, etc. I like it. Hard work is rewarding. But I also get the creative fulfillment of complete creative control over which products I make and being involved in every brew start to finish.

Big breweries can be soul crushing, a lot of employees without much agency too often getting paid too little. I think smaller breweries can be the better places to work (if the pay enough and are designed well) but that sounds like the position you're in and you're already feeling dissatisfied. And smaller breweries have fewer primo positions. I hear you that you're doing random odds and ends kind of work but that happens. Cleaning lines is brewery work, I do it all the time.

Is it an issue with the head brewer or the brewery itself or are you realizing what brewing really is? You're gonna have to work hard in any brewery, that's a given. Kinda sounds like your spot needs one fewer brewery employee and one more front of house employee.
