Been thinking about your budget situation since you need to order today. Honestly, I disagree with going super cheap on the stand just to save cash for the hub. Flimsy stands wobble constantly when you type, which is incredibly annoying. its better to split the 150 budget evenly. For hubs, I've compared the Ugreen Revodok Pro 109 9-in-1 USB-C Hub and the Satechi Slim Multi-Port Adapter V2. The Ugreen gives you more ports for cheap, but it gets pretty warm under load. The Satechi runs much cooler and matches the XPS build, though it costs a bit more. Pairing the Satechi with a sturdy BoYata Laptop Stand Multi-Angle Adjustable keeps you right around your budget limit and saves your neck.

Building on the earlier suggestion, you can save a ton of cash going with a budget stand. Im super satisfied with the Lamicall Laptop Stand LN02. It is cheap, sturdy, and works well to get my screen to eye level. No complaints here. For ports, Im happy with the Sabrent 4-Port USB 3.0 Hub HB-UMMC. Its a total steal and handles my mouse and keyboard with zero issues. Let me know if you need more budget recs!

In my experience dealing with the limited ports on modern XPS machines, you really need to look at the data throughput of the hub to avoid those connection drops. You dont want a cheap hub that chokes when you run a mouse and keyboard simultaneously. I highly recommend the Anker 555 USB-C Hub 8-in-1 because it handles 85W pass-through charging and supports 10Gbps transfer speeds. It runs about 45 bucks. For your neck, get the Rain Design mStand Laptop Stand. I've tried many over the years and this solid aluminum design is the gold standard for raising the screen to eye level. It costs around 40 dollars. That leaves you plenty of budget for a decent keyboard. Let me know if you want some good low-cost keyboard recommendations to pair with this, I can easily pull up some specs for you.
