A couple of things to consider
- a mobile GPU does NOT have same specs as desktop GPU (so be careful any assumptions you make based on desktop GPU model specs and reviews). I have NOT looked in detail at the mobile RTX 4060, and for simple H.264 streams it will be plenty (overkill), BUT, if you want this laptop to have a long life, then you may want to see look into AV1 compatibility ... just something to be aware of. If you are only thinking a 3+ yr life, then probably not that important. If your computers tend to last a lot longer (as mine do) then a little future-proofing may be warranted...
- Another thing to be aware of is the real-time video encoding (be that OBS Studio or Resolve) is computationally demanding (which means heat). All but the beefiest workstation laptops will tend to thermally throttle at some point (with that happening much sooner, on average, with consumer models, a little later on gaming rigs, and much later on the well-made, much more expensive workstation models). For short videos, probably not an issue. But, if you spend hours recording multiple takes, then hours more editing... learning how to monitor for thermal throttling (make and model specific) and how it will impact your specific workflow is probably a worthwhile thing for you to do.
Depending on your level of computer sophistication, I tend to get the smaller SSD from the OEM, and then upgrade on my own for MUCH less (but I know how to image drives, use original drive as an external backup device or better yet laptop with 2 drive slots where is keep original drive as OS drive, and add larger data drive, etc)
Hopefully you are getting a great deal on that laptop as it is 2 generations old at this point (and known for being power inefficient, which impacts battery life and heat issue mentioned above.. both of which may be non-issues for you)
