I have not had a chance to look through the full list, although have not done the detailed analysis required for any name. The strategy of a portfolio that has mainly ..com, but a mix of some other extensions, makes diversification sense. The ones in ngTLD are in .online which is a good extension. I don't know the .uk market, but having some country code makes sense.
I agree that many of the name + number ones probably are not sellable, although certainly some in that category sell. If one is doing numbers, 360 is a good match with some names that are suitable to for example 3D viewing. I might see your bridges or spacetravel working this way.
Some of the names that struck me as possibly good include the following.
FindTheatreTickets (com)
CoinDeskDaily (com)
CrabDiner (com)
FoodFest360 (com)
CryptoWatchDaily (om)
Bridges360 (com)
SpaceTravel360 (com)
Spaceflights (online)
VisitAsia (online)
jockeys (online)
I think possibly there is a mismatch between your sales venue and the quality of the domains. While it is true that some sales on Sedo are in the low $$$ range, most are higher. Even though it is 3 words, I actually feel FindTheatreTickets is potentially a good sale.
I would evaluate each name in your portfolio, decide which are indeed quality and leave at Sedo. For some others try to get low $$$ or even $$ for them through venues that sell more at those prices and where the commission structure makes it worthwhile. The $60 minimum at Sedo makes it not worthwhile to sell a domain name there for $100.
I think the primary question to always ask is
who might be the end users for each domain you acquire, and what advantage that would offer them. I cover that idea in a
post at NameTalent here.
You may also find my post on how to
evaluate whether a domain name is worth investing in. It offers 18 things to look at, that starts with listing categories of end users and the value they would obtain from the domain name.
While others have offered good advice in the thread, I would not be overly discouraged. I do see some good ideas in your list, an as I said originally, no matter the names, most will not sell in any one year. I really wish you every success in domain investing.
