Your options won't prevent you from getting into uni necessarily. Although they are considered soft it really depends how you do in them.
The Welsh Bacc is a difficult one because while it is accepted in most universities it isn't held in very high regards and with your other options it might limit you.
Your options definitely won't hinder you from getting a job as a primary school teacher. Some of my friends have gone on to teach primary with little to no A-Levels. However they might prevent or at least make it harder to get into a Russel group or a 'good' university if that matters to you.
It really depends on the rest of your application as well. Extra curricular things, personal statement and all that.
