A few thoughts for you, as I have slowly been building up my own electronics workshop at home on a budget for a while now !
Your initial budget is tight !
At the moment both Rigol and Siglent have good deals going on their older DSO model scopes as they are refreshing their ranges. But even then to get a half decent scope with serial protocol decode is around £370 - I know as I bought one last week. But even at that price the FFT is pretty poor. If you are going to use it for SPI work you probably want 4 channels. If you want to make it an MSO with logic analyser built in then add another £150.
An 8 or 16 bit Chinese clone of the Saleae Logic Analyser is a cheap starter for less than £10 to £40 on eBay and runs OK with the latest Saleae demo code (or PulseView).
An AWG £100 plus, Some cheap IsoTechs going on eBay for £160, but I make do with an arduino controlled fixed function 25Mhz board.
You probably need at least 3 PSUs (or a triple output one) lot’s of multirail projects out there, especially any older Audio Amps,
Be wary of the cheaper hot air rework stations. Some imports are just not safe, fused neutral rail, and poor safety interlocks causing melt downs.
You are missing (from your note, but probably already have most of them):
a) Some kind of air extraction, which is a must when soldering/reflowing
b) A decent magnifying lamp or a display and usb microscope - I use mine all the time as boards and components are getting smaller and my eyesight worse!
c) Fixed board holders, you always need 3 hands and it helps to avoid burning your fingers when using the hot air.
d) Loads of tweezers!
e) Flux cleaner or iso-prop (if you have money to spare an ultrasonic board bath)
f) Some fluxes and solder pastes need to be stored cool, so you may need access to a fridge (I use the wine/beer cooler!).--

I think CAD work is specifically not in the use case scenario here (unless I'm wrong but it sounds like scope creep to me...)

We have a spare NUC that may be enough for Debug and programming, but not for cad work. I have an AMD FX-8350 on mobo with 16GB DDR3 ram that is nolonger in use if wanted, will need a gpu, case etc

Volunteer here!Everything you have proposed sounds greatThe only specific thing I have to add right now is that the bench computer probably doesn't have to be a powerhouse (I'm unsure what specific tools need but can't imagine they'd be too intensive but small size is probably the biggest criteria. Something mini-itx at the biggest or maybe a nuc or similar like the laser cutter PC.Linux compatibility is probably a factor for open source tool chains
