I wouldn't do it that way, tbh. I think writers who have finished a novel without participating in critiques often aren't ready to have their whole first attempt marked up at once. Critiques are often hard to take until you get used to them. Probably best to risk a little bit and get a little bit of critique at a time, at first.
I won't usually do first novels anymore and know many others who won't, either. We quickly got tired of putting in possibly twenty hours or more work for someone we barely knew, only to get a snotty reply in return. The writer was expecting encouraging social comments like their family and friends may have made and real critiques from other writers sent them into meltdown mode.
It's also hard to get detailed, thorough, skillful beta reads out of the blue. It's a lot of work for them and a lot of people wanting the same. Many people will send it back with just a few general comments even if it needs much more than that. Others just don't have the skills yet. And beta reads should be a quick, final once-over polish, which a first novel, with no eyes on it but the writer's, is likely not ready for.
I'd slow down a bit and put up a chapter at a time in SYW first, including a short synopsis of the entire novel with each chapter.
As you go, be sure to critique for others as well so you can form partnerships. Also because there are so many common errors/problems we see in other people's work that we don't see in our own. It's an excellent way to improve writing skills. And, it's only fair. People are more likely to help someone who is giving them something back.
Keep your original draft in case you later feel like you've "over edited." Just disregard any suggestions that you don't agree with, which will be many. If more than one person says the same thing, consider it again but still don't change it if you don't see a good reason to.
First novels are typically riddled with problems that the writer has no idea of, and often the same errors throughout. As you get each chapter back and re-write it with the critiques in mind, be sure to go through the rest of the manuscript and change those repeating things there, too. People tend to quit sticking with a novel if it seems the writer either isn't listening or expects the critiquers to mark the same things again and again rather than do their work themselves.
It's important to seem appreciative of people's efforts. Always say thank you and don't argue with them, even if it's not a useful critique or they say something that sounds ridiculous. It's always up to you to use or disregard any suggestions.
Throughout, keep in mind that people will often hop in and out and just do a chapter here and there. That's fine because you can benefit from what helps and just disregard what you know they're missing from not having read the whole thing.
Once it's been put through SYW a chapter at a time, see if you can get some beta readers/swaps for the final, overall polish.
That's how I'd do it, anyway. Good luck. And huge congrats on finishing the draft!
