Choosing a new laptop for Sims 4

@Chocopug  A laptop with a 1650 should be able to run all current Sims 4 packs together on ultra graphics settings, and quite smoothly too when the game itself isn't causing slowdowns.  (This is a problem on even the strongest systems.)  If you like to use "high poly" (high-resolution) custom content, that might increase the demands of the game beyond the point at which a 1650 can handle ultra settings, but that would depend on the cc items in question, and it's not relevant if you don't use cc at all or don't mind getting rid of items that cause problems.

The other question is whether future expansions will be more demanding than current ones.  That hasn't been the case recently, and a 1650 still gives you a reasonable buffer to account for future packs; I'm just saying it's a possibility worth acknowledging.

Still, a 1650 should always be able to handle a mix of high and ultra settings, so if you're fine with that as a worst-case scenario, then there's no reason for you to spend the extra money on a 3050.  Both of these laptops are reasonably well-built and should have about the same lifespan as well.
