In terms of the cost of getting it, I doubt that a LAPL has any advantage over a PPL. In terms of what you can do once you have obtained it, then the PPL offers more possibilities and you will not incur the additional cost of having to upgrade from one to the other. A microlight licence will be cheaper than an EASA PPL but it will not cover all the things you mention and some of the conversion routes will close meaning you could finish up paying a lot more.
