maryreed17 This laptop should be able to run all current Sims 4 packs together on high-ultra or ultra graphics settings. The impact of custom content will depend on how the cc is made, as in, whether it's more demanding than regular game items. But you can always experiment with the cc and the settings.
I checked a few different sites and didn't see anything better for the same price, and the options with the same graphics card are gaming laptops, so they'd be larger and heavier. The cheapest model I found with a faster GPU, one capable of ultra settings with some room to spare, is a bit more expensive and also a gaming laptop:

I'm not saying you need an upgrade over the one you've linked, only that it's available if you want it. But if you're fine with potentially "only" high-ultra settings and you like the laptop you found overall, it's a perfectly viable option.
