The Iron Throne gets its piece, of course. Maidenpool or Stony Sept would be good options for growth, if House Tully had more influence/power over their lords.
We don't really know much about city governance and economics work in Westeros. We know that city charters are a thing (because The World of Ice and Fire mentions that Fairmarket, Lord Harroway's Town and Saltpans where denied them), but what would be in such charters is not, to my knowledge, ever specified. We also know that Aerys II apparently raised and lowered tariffs on Oldtown, Lannisport and King's Landing according to his fancy, suggesting to me quite significant royal authority over chartered cities (if indeed these places have charters).
Going by medieval European customs from England and the HRE it was however the crown more so than the local nobles who benefitted from city developments. Chartered cities got some liberties to do their own things outside of the feudal system, replacing a local lord (or bishop) with their own, usually guild based, semi-democratic and meritocratic governance. The local lord might of course benefit from the growth that having a market and some industry might bring to his region but since he wouldn't directly benefit from tax and tariffs of the city (which would go directly to the crown), I would say the English and HRE case seem to suggest that the crown is (apart from the city itself of course) the principal beneficiary from the wealth of cities.
In the Westerosi case the mention of Aerys II's tariff policy also seem to suggest to me that the Iron Throne exercise quite a lot of influence over the cities. Though again it is highly speculative, since GRRM devotes little attention to the affairs of cities and Westeros appears to have no equivalent to the European medieval commune movement to temper its feudal nature.
For a realm the size of England or the HRE, I would agree. Given that Westeros is the size of South America, each kingdom is effectively England or the HRE to itself (several times over). Granted we don't know much about the function of cities, but we do know they are different in many ways (such as lords ruling over them rather than the limited self-government cities of England and the HRE had), and we know that feudalism has been stronger in Westeros (possibly due to its size) than in real life kingdoms for a longer period of time. Hence the existence of offices that are deputy-kings unto themselves (the Hands) and kings unto themselves (Wardens).
So while the crown would get its tithe, the clear beneficiary to any city that exists is the kingdom it resides in and its Lord Paramount. It's probably why no new cities arose under the Targaryens save for King's Landing; a riverlands with Maidenpool as a rival to the capital would divert more trade to the Trident and away from the Blackwater Rush, strengthening the Tullys at the expense of the Iron Throne.
As with Duskendale, the Targaryens weren’t interested in letting other cities “vie for trade with King’s Landing,” (WOIAF, p. 118) as the Iron Throne gets 100% of the income from King’s Landing trade and would get a smaller cut from any other lord’s port. In fact, if you look at Targaryen development policy - most noticeably the royal highways built by Jaehaerys I - the whole point is to route traffic through the capitol. Thus, the River Road abruptly turns south at Lord Harroway’s Town straight to King’s Landing, rather than continuing along the bank of the Trident to Maidenpool; Maidenpool in turn is on the Rosby road, so that you have to travel to King’s Landing before taking your goods anywhere important via roads.
So I think the story here is the weakness of the post-Draconic monarchy driving policy to favor the King’s personal income and thus the capitol. If the Targaryen monarchy was more of a genuine nation-state, you might well see the Kings doing more to promote economic development more widely.
