i don't have much experience with different telescopes, but i do understand the concept when it comes to aperture size.
i've owned a 5" celestron on an equatorial mount,

my suggestion is, yes... look at the planets. but there are just 2 that are interesting. 3 if you count mars. the polar cap is supposedly visible when it is on the same side of the sun as us. i've never taken the oppurnity to look.
in my 10" scope, saturn is amazing to look at, as you can very cleary see the ring. then a few minutes pass and you've seen enough.
jupiter and it's 4 moons are visible, along with few of the color bands in it's atmosphere... which also is amazing to see. but still, a few minutes pass and you're done. now what? venus is kind of bland... it looks like a very tiny half moon and there is no noticeable features. the moon is great to look at as well. especially when it's less than half.
so, i've been told that the common form of a telescope that we all know, is the best for planets.
something like this;
https://www.amazon.com/dp/B00LY8JWAQ?tag=theplanetsorg-20&linkCode=ogi&th=1&psc=1but the aperture is so small, that it's useless for deep sky objects. you need to let alot of light in to see detail. the planets are so bright, it's not really an issue. i'm not sure if saturn moons are possible to be seen from earth, but if they are i would think you would need a large aperture to see it.
my point is, i'd hate to see you buy a scope with just looking at planets in mind, because there are so many things to see. like you, i got interested because i wanted to see jupiters moons. i could barely make them out with my binoculars, and i decided to upgrade. well i bought the celestron 5". it was fine for viewing, but it was really hard to find stuff because the cheap aiming device it came with. once i bought the orion and saw how well the red dot sight worked, i basically know i'll never use the other one. on a side note, that equatorial mount is very nice, anyway, after i got done looking at the planets i said to my self what now? i ordered a few night sky books, and fortunately came across this one.
https://www.amazon.com/Field-National-Audubon-Society-Guides/dp/0679408525/ref=sr_1_17?dchild=1&keywords=night+sky+book&qid=1593809292&sr=8-17the other two were junk, and really terrible at explaining things. the audubon society one is excellent in that it will show great maps of each constelation and where all the deep sky objects are in them. on my apartment balcony i could see the constelation lyra and there is a nebula called "ring nebula" in it. after about 2 hours i finally spotted it, and that was what got me hooked.
so, i'm rambling, but i'm still trying to make a point here.
i think if you get the best telescope for planets it will be like this. i'm exaggerating to help make the point
scope A,
planet viewing score 10/10
deep sky objects 1/10
scope B
planet viewing score 7/10
deep sky objects 10/10
something like that celstron 5" would be great for you i think, just know, that the aperture is what makes the scope, not magnification. they may tell you , 'this can magnify up to 200x' but that is useless.... about 20-60x zoom is about the range that is usefull. so, you're basically paying for aperture....and also, another thing that gets overlooked, 8 inch isn't 2x's better than 4"
8 inch circle covers about 50 square inches
4 inch circle covers about 12 square inches
so buy as big as you can afford.
anyway, i'll shut up
what i meant about the star finder tech, is they are preprogrammed with all the messiar objects and lots of the stars where all you do is dial in what you want to see and it goes straight to it.
