WhatsApp lets you export chats as txt, but I guess that's lossy.. e.g. I'm not sure the emojis will be there. Surely no attachments or voice messages.
As for extracting from the backup DB, they'll be encrypted..

The limits are supposedly due to email size limits but, as they also apply when exporting to non-email endpoints like Google Drive, I suspect they're more to do with preventing people from moving their chats to other services.
And yes, the db is encrypted.
Since some months (years?) ago, WhatsApp lets you set up your own encryption password for the DB backup. I set one up and used https://github.com/ElDavoo/wa-crypt-tools to get access to the decrypted SQLite and run some analytics over my messages :)
