Splitting code into libraries works better, it's simpler and faster. The only thing micro services bring to the table is being to deploy updates independently (although this is also possible with libraries). If you don't need to deploy independently then micro services are useless complexity, if you can't deploy independently then you've got a distributed monolith.
