@jjosierenee The laptop lines you linked aren't bad, but the best options, the ones with dedicated graphics cards, are either more expensive or are entirely unavailable. If you get a laptop with an integrated card, you may not be able to play on more than medium settings. But in the $700 range, there are lightweight laptops that should run all Sims 4 packs together on high settings, and a few gaming laptops that would handle ultra settings.
In terms of gaming laptops, there really aren't many that are also lightweight and inexpensive. This MSI is 4.1 lbs though, which is about a pound lighter than a typical gaming laptop, and should run the game on ultra. Its one drawback is its small hard drive. While 256 GB is more than enough for Sims 4, Minecraft, lots of small apps, and plenty of text documents, it might not be enough if you decided to install other games as well.

Since you were looking at the Aspire line, this one is $700 and has the same specs as the MSI above except for a 512 GB hard drive. It's heavier though, at 4.7 lbs.

On the very lightweight end, this Asus Zenbook is 2.7 lbs and has a graphics card that should handle all Sims 4 packs on high settings, although ultra is probably out of the question. It also has a 256 GB hard drive.

This MSI Modern is the same weight and has more storage, but its graphics card is somewhat slower, maybe 25% in games. It's also $50 cheaper.

If you're willing to go a bit over $700, these two have the same graphics card as the Zenbook and a 512 GB hard drive. They're just under and a bit over 4 lbs, respectively.

The point is, you can find a good balance among performance, weight, storage, and price, however those details rank in your mind. These are all good laptops; the best option is the one that best fits your needs.
