There's not a whole lot of choice of interchangeable lens cameras within that limited budget.
The D5300 would be a significant "step up" in many ways, from your Canon point-n-shoot "super zoom".
One problem is that the D5300 two lens kit (which is within your budget) comes with the AF-P 18-55mm DX "VR" and AF-P 70-300mm DX lenses. This is backwards... the telephoto lens would benefit from VR image stabilization much more than the shorter focal length zoom does. No doubt, Nikon does this to keep the cost down. There's a VR version of that 70-300mm lens, too... but it costs about $50 more and they don't offer it in kit with the cameras. (Buying the with only the 18-55mm and the better VR lens separately is possible, but ends up costing a great deal more... around $1000!)
Another possible problem is that the Nikon D3000-series and D5000-series cameras don't have the in-camera focusing motor, so only the AF-S and AF-P lenses will autofocus on them (some of the earlier models also are not fully compatible with AF-P lenses). You have to step up farther to the D7000-series and higher models to be able to autofocus Nikkor AF lenses, which don't have a focusing motor built into the lens itself and rely upon one that's in the camera body instead. Mostly those are older lenses, but some are still in production (such as the Nikkor 200mm f/4 micro and the Tokina 100mm f/2.8 macro lenses.) This may or may not matter to you, for your purposes.
Canon actually does something similar to Nikon with their most entry-level kits. Canon often includes an EF 75-300mm "III" lens with them, which lacks stabilization, has slower "micro motor" focus drive and simply doesn't have very good image quality at the 300mm end. I recommend avoiding the EF 75-300 III.
However some Canon DSLRs can instead be purchased in two-lens kits with the EF-S 55-250mm IS STM lens, which is much better in almost all respects. The older Rebel T6 (18MP, EOS 1300D outside N. America) is currently being offered with EF-S 18-55mm IS STM and EF-S 55-250mm IS STM lenses for $549. This is a very entry-level model, using a 1 generation older sensor and a 2 or 3 generation older image processor.... and lacking a lot of features found on the "step up" models.
The newer and much improved Canon Rebel SL2 (EOS 200D) uses the same simple AF system as the T6, but has many other features and would be a nice travel camera because it's the smallest/lightest DSLR on the market (even lighter than some mirrorless cameras). But it's over your budget in two-lens kit: $749 with EF-S 18-55 IS STM and EF-S 55-250 IS STM.
Older and not as compact, but also a much more full featured than the T6, the Canon Rebel T6i (EOS 750D) is being offered with the same lenses for $749 too. This model has a more advanced AF system than the SL2 or T6.
You also might want to consider some of the mirrorless models, which can be quite compact and nice for travel. Some two-lens kits offered among those include:
Canon M100 with EF-M 15-45mm IS STM and EF-M 55-200mm IS STM lenses... $679. This camera uses the same 24MP APS-C sensor as the SL2 and T6i mentioned above. Note that the M100 doesn't have a built-in viewfinder. You have to use the LCD screen on the rear of the camera to compose images.
Some of least expensive mirrorless
with a built-in viewfinder include:
Panasonic Lumix GX85 with G Vario 12-32mm and G Vario 45-150mm lenses is under $500. This camera uses a smaller micro 4/3 format sensor and has lower 16MP resolution. It has in-camera stabilization, instead of in the lenses.
Sony a6000 with E-mount 16-50mm OSS and E-mount 55-210mm OSS lenses is selling for $748. This 24MP, APS-C camera.
Olympus E-M10 is $748 with Zuiko 14-42mm EZ and Zuiko 40-150mm R lenses. Like the Lumix above, this is a 16MP micro 4/3 camera and uses in-camera stabilization.
Canon M50 with EF-S 15-45 IS STM and EF-S 55-200 IS STM lenses currently sells for $879. This is one of Canon's newest models. I think I read that in 2018 it was the #1 selling mirrorless camera in Japan.
Fujifilm's X-T00 is their most entry-level model, 24MP APS-C format, with in-camera stabilization and offered in kit with XC 15-45mm and XC 50-235mm lenses for $998.
Have fun shopping!
