Pet peeve here. If you accept an offer from a publisher, I don't care what kind of publisher, you better know what your publisher does for you.
Does your publisher just put your book out there?
Do they do edits at no charge to you?
Do they do the cover art at no charge?
Do you have input on the cover art?
Many of these are spelled out in your contract. So please, read your contract. You are signing a legal binding agreement with the contract, make sure you know what you're getting into.
There are also things like:
Does your publisher do any marketing for you?
Does your publisher arrange blog tours for you?
Do they give you copies to give away or must you purchase them?
Some of these may or may not be in your contract and these are things you need to know and understand.
If you don't know something, ask your editor and/or agent. Or research the answer by talking to other authors published by that publisher.
Don't assume your publisher is doing something unless they've told you. If you're not sure ask. You won't appear stupid to the publisher, they know there are so many options out in the world.
An example of this, I was explaining to some writing friends about my publisher putting my books into Amazon's KDP Select and how it worked out for me with the 5 free days KDP Select has.
Another published author wanted to know when she was going to get her 5 free days with Amazon and how did she set it up.
Both myself and another writer explained, that was up to her publisher, she needed to talk to her publisher. This author continued to go on about how if I did it why couldn't she. I patiently explained my publisher did this, not me. And since they published her book she needed to discuss with her publisher, she can't take the book the publisher published and make it free without them agreeing and her publisher making it free.
This is just one example. There are so many options now-a-days. Writers/Authors need to be informed. Writers/Authors need to do their homework.
And just because someone else is doing it doesn't mean its the right fit for you. You have options, explore them all.
