Any tips etc on how to use my day to day PC as a pruned node with the blockchain data stored on an external SSD?

So I've been stacking sats for quite a long time and been wanting to spin up my own node with my current hardware. I'm not the most technologically inclined with respect to running a node, but I understand the general gist of them and primarily just wanna validate my own transactions, so excuse my ignorance if any. I don't necessarily want to buy extra dedicated hardware/devices to run a node other than an external SSD that I have in mind.

I have my Ledger Nano X that I wanna use with Sparrow wallet. I've been using Ledger Live for pretty much ever, but I also want to move away from that.

My day to day PC specs are as follows:

2019 iMac
64 GB DDR4 RAM
2 TB fusion drive
3.6 GHz 8 core i9 processor

The SSD that I plan on buying to store the blockchain data on is the Sandisk Extreme pro with 1TB on it.

I know I have to download Bitcoin core onto my PC and direct core to store the blockchain on the external SSD (like I want), but what else would be required from there other than running certain command lines for a pruned node? Also, I don't intend on having the node up and running 24/7 and will let the blockchain sync up every now and then to stay updated. Thanks.
