It is extremely off putting to providing any kind of answer and help when the first thing anyone does is to look for perceived problems with cruise ships. Cruise passengers have as much right to be there as people flying in. Bergen is one of the biggest cities in Norway, and many of the passengers go off out of the city on ship's tours. Bergen is as busy (if not busier) with land based tourists (and those who have flown in for a few days) as with cruise passengers, especially in August.
Like many markets round the world the fishmarket, I think, is best seen as early as possible, around 9 to 10am. Not only is there more stock to be seen, but it is less crowded with tourists. You may find this history of the 900 year old market to be interesting- https://en.visitbergen.com/things-to-do/fish-market-in-bergen-p822253
Ulriken is very easy- either the dedicated bus from the City Centre, or scheduled bus or tram- see here- https://ulriken643.no/en/find-us
Likewise- the Fløibanen. If you are a morning person get there early, it opens at 7.30am, so you can be there long before the tourists (cruise or otherwise) arrive. It opens that early because the railway is also transport for the locals who live on the hill as much as it is the tourist attraction many see it as. From the Clarion it is only a short walk away.

Take the train up then walk down hill. It is not well known that there are three intermediate stops on the railway (all of which are on Google maps) mainly to serve the locals. So you can start to walk down, then use one of those other stations. There is no reason why you could not walk down to Skansemyren, hop on a train down to Fjellveien, walk down to Promsgate and take another train up or down, or any variation of that theme. I have done versions of that theme several times.
I would have scheduled this on the Wednesday then the afternoon Fjord Cruise, but it looks like you need to do that on the Friday.
For the Aquarium either take the Skyss Bus #11 or the much more fun route is to take the ferry from the Fishmarket directly there (it also has 2 other stops on it's route)- https://en.visitbergen.com/things-to-do/discover-bergen-by-boat-a-great-way-to-see-the-historical-sights-p1651263 . You could do that on the Wednesday afternoon after your Fjord cruise.

The Ice Bar is only a short walk from the Magic Hotel. See this Google Maps extract- https://www.google.co.uk/maps/place/Magic+Hotel+Kl%C3%B8verhuset/@60.3951553,5.3129582,16z/data=!4m9!3m8!1s0x463cfc02ac0ffd19:0x2036ebf2ccd062d5!5m2!4m1!1i2!8m2!3d60.3942119!4d5.3227858!16s%2Fg%2F11d_z7zbd3?entry=ttu
Your hotel is marked and the bar is just by the Nykirken at the top left of the map.
