So, what is your question? Looking to upgrade the macOS onto your Mac?

Installing the macOS:

Determine which Update(s) will Install:

I. Verify Compatibility:

A. Start Here: Learn About Compatibility and how to Identify your Specific Mac Model - Apple Support

B. How to Verify:

I Reveal your Model:

What is the Model of your Mac? To find out...

1. Go to: Apple menu
2. Click: About this Mac
3. View: Second Line-Down

then...

II. Compare the Results:

See if the Model you found is shown here: macOS Sequoia is compatible with these computers - Apple Support

III. If Compatible:

Back Up your Mac First:  Be certain you Create a Time Machine Backup of your Mac, so that way you can have something to restore your Mac from, should anything go wrong with the reconfiguration.

I would suggest an WD SN850X or SN750 depending how fast you want in a TB enclosure. I use both of these drives. I use an Acasis and Satechi TB enclosure. The Satechi uses a faster chip than the Acasis. I use these fast drives as bootable so I can test various changes to the OS before I make any internal updates.

And if you intend to use that external drive as your boot drive then be aware that booting from an external drive on an Apple Silicon Mac can be tricky because of how macOS is locked down these days.

In my opinion you should use the M4 Mini’s internal drive as your boot drive and use the external drive for storing your user data.

Also be ware that using this drive with a Thunderbolt 4 port it will never be able to achieve the advertised speed.

The M4 Mac mini's internal storage drive is not upgradable.

What you'll need for the WD_BLACK 1TB SN7100 NVMe, is an external NVMe enclosure that plugs into the Mac Mini's Thunderbolt/USB-C port.

What Stand & Hub with SSD slot are you considering...?

Your best bet, is to check the spec's of the Stand & Hub for NVMe compatibility.
