So, if you are super excited to get into Galaxy's edge in the morning, hit one or two early entry attractions and then line up at the gate to big thunder trail by Red Rose Tavern and wait for Rope drop - then you can head to Rise of the Resistance, and then to Millennium Falcon, and explore before things get busy. You give up the best time to hit the rest of the park this way, but if GE is your main priority then you'll enjoy exploring and browsing the various shops, possibly even grab some food etc.
However, if you are ok with waiting, what I like to do is spend the morning going hard and fast at the rest of
Disneyland. Use EE to knock out any Fantasyland attractions you want to do, and make use of
Genie+ as the morning wears on to get most of the big attractions done. You can do quite a bit before noon, even on a busy day. Have lunch, then take a nice break, and schedule MFSR LL for around 4pm. Then come back to the park around 3 and head to GE and spend the afternoon/early evening exploring. If you want to spend on an ILL For ROTR, feel free - get a return time for early evening and go crazy. Otherwise, plan to hit it around 8pm (note this comes with a risk that if the attraction goes down in the evening, it may not come back up. However since it sounds like you have multiple days at DL gambling on your first day doesn't hurt too much) as the wait comes down quite a bit around this time. Somewhere in there join the walk up list at the cantina. If you want to build a light saber, you can make a reservation to do so - there is often availability day of. Not sure how the Droid situation is, but you can also do that stand-by so you don't need a res. Anyway, you can spend the afternoon/evening in GE and soak it all in before going off-world and catching any other stuff you didn't do earlier in the day. If you like the mobile gaming aspect, make sure you've got the latest version of the Play Disney app - there are mini games you can do and scavenger hunts of sorts that can be fun on the "Datapad." And of course, if you have Magic Bands, you can try the Bounty Hunter game.
Your mileage may vary - I just really like the energy of GE in the afternoon, even if it is a little crowded. But that's just me. Whatever you choose to do, I hope you have a great day tomorrow and that Rise stays up all day long.
