For my general development. What else do wallets exist that have an cancellation option?
I apologise for the off-topic question.

Not an off-topic question.

hosseinimr93 has already provided you with one of the wallets canceling unconfirmed bitcoin transaction can be possible which is Bluewallet:

Fee & Transactions control

Provides you a fee estimation targeting confirmations in 10m, 3h or 1 day. With real time calculation on how much to spend. Ability to Bump and Cancel sent transactions with "Replace-by-fee" (RBF) or with "Child-pays-for-parent" (CPFP).

Also you should be able to calcel an unconfirmed bitcoin transaction on Trezor Suite:

The "Speed up" and "Cancel" buttons can be found below the pending transaction in the "Activity" tab. Remember, you need to pay a fee (gas) to be able to speed up or cancel a transaction.

What does this mean?
"Provides you a fee estimation targeting confirmations in 10m, 3h or 1 day. With real time calculation on how much to spend. Ability to Bump and Cancel sent transactions with "Replace-by-fee" (RBF) or with "Child-pays-for-parent" (CPFP)."

Do I always have at least 10 minutes, 3 hours or 1 day to cancel the transaction?
