@jbflygirl Since you're open to both, I'll list some gaming and non-gaming laptops and what you might expect from them, and you can decide for yourself which direction to go.
This laptop should handle high or high-ultra graphics settings before you take custom content into account:

This one is maybe 10% faster in gaming performance, and also has a much prettier, higher-resolution screen. You might need to reduce the resolution in-game for best performance (it would be fine to experiment), but the extra pixels would be great for everyday non-gaming use whether or not you played at that resolution:

This one has a similarly pretty screen, slightly lower-resolution (but significantly higher than standard) but also brighter, and the same processor and graphics chip, meaning roughly the same performance. I wouldn't try to use touch display in Sims 4—I've heard only bad things about it—but if you might find it convenient in other contexts.

These are in the same performance category as the second one but with a standard, normal-resolution screen:

These are either under or just over 4 lbs., so they'd be easy to carry around. There are more options similar to the last three but a bit more expensive and not clearly better, so if you want something in that category but with slightly different details, let me know.
For gaming laptops, it's harder to find lightweight models, but this one is 4.2 lbs. and could run all current Sims 4 content on ultra settings. It also has a high-quality, bright screen:
https://www.lenovo.com/us/en/p/laptops/ideapad/ideapad-500/lenovo-ideapad-pro-5-gen-9-(16-inch-amd)/83d50003us
This one is somewhat faster in gaming, with a higher-resolution but not as bright screen, and is 4.5 lbs.

This one is 5 lbs., with a standard screen and the same performance as the Dell above, but is also cheaper:

This one is 5.4 lbs., still with a standard (though high-refresh rate) screen, and is the next tier up in performance. It could handle anything Sims 4 could throw at it for the entirety of the game's lifespan.

Here again, there are more options that are equivalent in specs but more expensive, so if there's some detail you don't like about these, let me know.
As a side note, I've seen people report cc collections of up to 300 GB (not a typo), so if you have a problem, it's nothing compared to certain other players.
