Consolidating UTXO help

I want to consolidate my UTXOs today or very soon before the bull market really gets going. I think I know how to do this, but I want to check here before doing anything because I know there are smarter men than me out there that may be able to help me out.

So I have a Trezor One that has two accounts on it. A Legacy Segwit Accout and a Default account. My Bitcoin is split between the two accounts.

I plan on sending the Bitcoin from the Legacy account to the Default account. Once it is all in the same account, then sending all of it to a new single address in the Default Account so it should have one a single UTXO.

Is that correct?

Also, I would like the transactions to be included in the next block or two once I do it so that this isn't a multi-day process. But, I also don't want to overpay. Where can I check to see what a reasonable transaction fee would be for today?

Edit: Also, I have ~50 transactions total on this wallet. Would that create enough UTXOs to even worry about?
