Ipad fell into tub, drying methods used but still dead. Is all data irretrievable? SIM card won’t eject, btw.

iPad has no protection from moisture. If exposed to water, the iPad is very likely beyond repair. If the iPad will not boot - and you are unable to successfully enter your passcode, any locally stored data is unrecoverable.

iPad uses an encrypted file-system; the passcode unlocks the Secure Enclave (this being the iPad security chip) that contains the only copy of the encryption key - this key being required to access any locally stored data.

As described, unless you have a pre-existing iCloud or iTunes backup of your iPad, you have lost your data.

Water and electronics do not mix.

Unless you have made previous backups of your iPad? Yes, the data is, now, irretrievable and is gone forever.

Sorry.

With the exception of your iCloud backup, you will need to get expert service and support at the Genius Bar.

Yes.

Backups need to be made and maintained before the device is destroyed.

Apple does not offer data recovery services.

The principal difference between the 2021 iPad Pro 11 and 12.9” models is the MiniLED XDR screen. You’re unlikely to be disappointed with the larger, brighter, higher-contrast, more power efficient XDR display. Just keep them (along with any iPad) away from water!
