Bitlocker query

in my humble view I would look elsewhere than bitlocker for the performance issue

What actions are you actually observing as being less performant than you would expect? Bitlocker would only have an effect when read and writes are occurring on the drive. 

That is a mobile CPU so I'd be looking at the windows power profile to see if it's set to maximum performance: https://support.microsoft.com/en-gb/windows/change-the-power-mode-for-your-windows-pc-c2aff038-22c9-f46d-5ca0-78696fdf2de8

At least change it to maximum if it's not, do some tests and see if it makes a difference

Boot up is quick but not astonishing (20 seconds) - once running, it seems to hesitate when opening programs.

This was a blank SSD which is now running just basic programs (Thunderbird & Firefox)

As far as I am aware - Windows 11 power profile only affects the battery life by adjusting sleep settings and preventing certain software from running - not the actual processing power ?

Also, do you have an M.2 SSD stick set to NVMe mode in BIOS/UEFI? An SSD used in SATA mode isn't fast, something like 500MB/s compared to NVMe starting at 3,000MB/s

I don't know much about this, but my understanding is that SSD  speeds under 600MB/s are a limitation of the physical SATA interface, but what is set in  UEFI would be the logical interface - sending  SATA commands over the PCIe interface. The data is still going over PCIe, so  500MB/s seems implausibly low - unless you have actually measured it.
