A couple of my favourite 'newer' altcoin projects are: BAT and VeChain. They all got great room to grow in a bull market. With strong teams and products. Actual live products that are working, with users who use them daily.
Other interesting altcoins are: Callisto, ADA and Chainlink. Especially Chainlink and LINK is interesting if they can suceed with what they are working on.
Your choices are almost good. But there are some things you need to watch out for. For example, Vechain was hacked recently:

I guess Chainlink and Link are the same projects? Anyway, LINK is one of the projects that should be invested.
