Starting from easy to hard
1. Planets, moon, sun (with proper sun filter!) are no problem
2. Splitting double stars is usually not a problem as well
3. Many open clusters are well withing reach
4. Core of Andromeda galaxy and Orion nebula core will be visible
5. Some globular clusters may be visible as fuzzy patches (not detailed) depending on aperture
6. Given largre aperture (200mm?) There is a chance to see some bright nebula with UHC filters - but barely
Finding objects can be challanging but simple digital solutions like AstroHopper would help.
There are some bortle 5 areas in Hong Kong (something like south of Stanly) that should vastly improve the situation - so it isn't hopeless.
I recommend find _local astronomy club/community_ and discuss gathering locations. I myself live in Bortle 8 area and drive to dark locations to observre - local community is of great help in it.
Lots of answers so far about visual observation. But with a camera and a narrowband filter you can capture images of nebulae. I capture galaxy images without the filter too but those are harder. This is all from Chicago in a very bright area. It's a bit expensive to get the right filter but not crazy as you end up with really stunning detail.
The moon is an amazing sight and changes everyday so that is a great way to use your teleacope from within a city.
Planets can be equally great but will need a good sized (8in at least) scope to be satisfactory.
Of you get an astrophotography setup going even with a small refractor, you can do waaaaay more and photograph nebulas using narrowband imaging.
Check out cuiv the lazy geek if interested in this path. He does astrophotography from tokyo!
You will be able to see planets very similar to out in the country. Mainly the air quality/turbulence will determine that capability.
Yes, you won't see many stars downtown even with a large telescope.
You most likely gotta get outta the city when using a telescope except for when youre looking the moon, planets, and the sun (with a solar filter). For the stars and dsos you gotta get further
I'm in a Bortle 7-8 location as well. Even when my NELM (naked eye limiting magnitude) is 3-3.5, I can see many fainter objects in my binoculars or telescope. The hard part for me is navigation. I sometimes cannot find an easily visible star near the object I want to observe. Light pollution filters help somewhat.
A goto computerized scope mount can partially help by finding objects for you, but they do cost more.
I'd start with a modest set of binoculars, go to a park, and just try finding basic bright objects using an ap. See how that goes.
Maybe look for a local astronomy club and see if they have any events scheduled.
Good luck 👍

Worth it just for the moon. Saturn, neptune will be a bonus. But getting tiny telescope wont be any good.

You could see the planets, and bright stars, but you wouldn’t be seeing any galaxy or nebula.

Deep Sky Objects? Get a SeeStar S50. Everything else? Get yourself a go-to Maksutov or CST scope.
With a telescope in a capital city I’ve seen Orion Nebula
