What should I buy with this?
The rules are pretty lax as long as it's loosely related to Software Engineering, Management and/or Business.
Heard of a large law firm, iirc, whose IT dept did that one year. they didn't require anybody do anything with them, just "here's the fancy $300 kit with all the parts ready". and they got very positive reactions and the people who din't want to play with the kits themselves had people they could pass their kits on to who appreciated them.
You didn't say what kind of Engineering your firm does, but there are many training portals that have popped up specifically geared toward engineering (pun intended) that might be what you are looking for.
WEB-300 course in particular https://www.offensive-security.com/awae-oswe/ It shows how vulnerabilities are found using code review and how to exploit them in lab environment.
There's a subscription based model for $2000 where you can pick a course and work on it for a whole year https://www.offensive-security.com/learn/
Signup for ACM membership and you get Oreilly access (usually 500$ per year alone) + academic papers and an email forwarding address for 200USD per year.
* NUMA-capable CPU. $3000 budget for a lower-end NUMA-server (say, 2x Xeon Silver, or maybe 1x AMD EPYC) gets you the hardware needed to start playing with NUMA (non-uniform memory access). Or any other high-performance computing part really.
* GPUs -- GPUs are very expensive right now, but an NVidia T4 is a bit over $2000 right now. A decent option to get into CUDA on your work budget.
* Software -- A lot of professional software is somewhere from $500 to $4000 or so. Matlab, IDA, EagleCAD, VMWare, SQL Server, Oracle, etc. etc. Pick a tool, any tool, that might benefit you or your team, and use the training budget to get a personal license.
* Networking -- $2000 is enough to start playing with various networks. Buy a bunch of Fiber-optic stuff and connect them together, switches, PCIe ports (ConnectX PCIe cards), fiber lines, transducers. SFP+, or SFP28 (28Gbit networks), 40Gbps, 100Gbps. VLANs, Cisco iOS, etc. etc. So much to play with, plenty of skills you'll gain only with playtime.
* Various other technologies -- Dell iDRAC, SuperMicro IPMI, etc. etc. Have you learned how to use and install these features? If not, surely there's a $2000+ server from Dell, SuperMicro, HP (or other server provider) that is close to your budget?
* Get that Talos II POWER9 computer to play with PowerPC.

A lot of the other discussion points about books and/or training are no where near $2000. ACM Membership is great but only $100 to $200 / year. IEEE Membership is similar. Unless you can find like 30 papers to download in the next 2 days, you're not reaching your $2000 budget.
Instead, the big-ticket items (obscure hardware, obscure software) easily gets you to $2000, $3000, or $4000 budgets in a single purchase. You should be aiming to blow-away your budget (and maybe spend a bit of your own money) and do something you normally wouldn't be able to do.
Err on the side of going way overbudget.
I know a good one if you use Sublime Text ;)
* https://learnui.design * https://css-for-js.dev * https://threejs-journey.com/ * https://frontendmasters.com
Or work on your communication skills. You can do this via mentoring too, but also a mix of books and things like stage/acting lessons.
I also recommend a https://www.masterclass.com/ subscription! No it is not programming but, I believe they great videos on a variety of topics.
The best part was that I wasn't ready to commit to a 6 week intense course but I could pay more (still within budget) to get a lifetime membership. I ended up doing the course during a later cohort.
Maybe some Management books as well, though my reccomendations there are unfortunately not as good. In any case books would be good for whatever is left.
At the current point in your career there might not be much point in certifications but if you did want any now might be an especially good time to buy the tests since just about everything can be taken remotely.
Linux academy has good cloud and DevOps training.
You could buy a ticket to Black Hat in Vegas. I believe they are around $1000. Not sure if buying it now would apply since the actual event isn't till next year.
As you're already familiar with the person's content and style, you're more likely to actually use what you bought. Plus, many creators offer team licenses on their premium materials so that you can share them with your team.
Execute program by Gary Bernhardt is definitely worth a look.
It happens that I wrote a book about Security and Rust :)
