Answer 1

It depends on your business requirements.
If you want all mailbox enabled accounts synced and managed from on-prem, then create the remote shared mailbox on-prem.
If you have on-prem processes or applications that send email to the on-prem Exchange Server and may send email to the shared mailboxes, then create the remote shared mailbox on-prem

If you are fine simply managing the shared mailboxes directly in the 365, then create there.

Its really up to you and what works for your company :)

It decided by whether you need to manage shared mailbox on local AD. If you don't need to manage shared mailbox on local AD, you could create them on Exchange online directly.

The only difference is whether you can manage it from local AD.
