Norway - City Tolls?

[2CV67]

We are off to Norway soon & know it will be expensive...

I just signed up for the AutoPASS system, so my credit card will be silently whittled away as I drive.

I see several towns, including Bergen & Stavanger, have a City-Toll system, but I can't find out if it is just an inconvenience or if it is downright dissuasive.
Has anybody any recent experience of driving & parking (not overnighting) in either town?
What is the toll charge & what does it cover?
Is visitor parking in such towns free/cheap/expensive/impossible?
Is there obvious outside parking instead?

Thanks for any tips!

Toll in Norway is never very high. You can easily visit and park in Bergen and Stavanger, no issue, all is very self evident.
