The loss of the $7,500 EV tax credit and the jump to 27.5% import tariff the US imposes on Chinese vehicles, the 2024 SE might be too expensive to bring to the US.
IMO, the current SE's small battery is a feature, not a bug. There are plenty of EVs (Bolt is the least expensive) that can get you to the family without stopping to charge along the way. The SE is built for fun--have you driven one? If the SE would be your only car, it would make weekly family visits more difficult than with a Bolt. Again, IMO, if you like driving fun cars, tell the dealer you've reconsidered your cancelation. You can always sell the SE later (perhaps at a profit) if the fun doesn't offset the inconvenience.
