Thanks for your question! It sounds like you’d like to stick pretty close to I-5 during your road trip, but if you haven’t seen it, I do recommend Crater Lake National Park, of course. It’s about two hours from I-5 via either Ashland or Medford. If that’s too far off-track, consider a stop in Ashland (just over the CA border) with a stay at Ashland Hills (nice for kids or just adults) and some family time in Lithia Park and downtown Ashland (filled with fun shops and dining experiences). For a more funky, fun stop, consider the Vortex at Gold Hill, just past Medford. Another nice stop is Grants Pass, where you can take a jet boat ride on the Rogue River or a day trip river rafting trip from Galice (just north of Grants Pass). In Roseburg, consider a drive up Highway 138 (the waterfall highway) with stops en route to walk to some of the most iconic waterfalls (short hikes, close to the highway). This detour will take you a few hours, but if you persevere, you could even make it to Crater Lake at this juncture.
