Is there any way a captured but non-ceded city can grow again?

In Civ 6 an opponent has to cede a captured city to you for it to grow again.

Is there any way around this - including with Wonders or Civics or anything else?

I have now wiped out a civilization before he could cede his cities to me - am I now stuck forever with non-growing cities?

On a related note if you decide not to raze a city as soon as you capture it - is there any way to raze it later?

(I can see this leading to ridiculous anti-pattern moves like allowing a city to be captured so you can recapture it again and raze it).

On another related point if a non-ceded city is captured by a third party - do you need to cede it to them or does the original owner? And what if the original owner is dead?

When a civilization is completely wiped out it automatically cedes all of their cities.

You must raze it immediately otherwise you need to get them to cede before the city will grow in population. As a side note you can force the city to grow with a worker removing resources such as the Jungle if it is close to another population in food.

NEW GAMEPLAY MECHANICS OR BUG FOR 'RISE AND FALL' EXPANSION

When making peace with an opponent the city automatically cedes even if you do not choose it in the trade screen. This is a major change, either they intended to remove the ceding system and forgot to remove it from the trading screen or they broke the ceding system.
