I believe Google Takeout produces your emails in mbox-format.
Dead easy to re-import that to another provider using a pythonscript or something.
Just remember to set up a gmail forward to your new provider for any straggling emails.

Then, if you've setup a new email account with another provider, you can connect using IMAP and copy your emails that way.
IMAP only download the index - everytime you click on an email, it'll then download it. When you have 150K emails, then you need to click on all that emails 150K times.
