Hi a very warm welcome to the site.
Good first place to ask is your setting, they'll know what opportunities currently exist and then use google and your Local Authority's (County Council's) website to find other professional development courses eg. to expand you knowledge about children's learning, child protection, first aid, risky play, forest school, food hygiene, creative activity workshops. The training can be areas you find interesting and ones your setting will expect you to attend.
This criteria is making sure you know there are many ways to enjoy your work, understand why it is so important and continue to develop your professional practice xx
Pages 149+ and specifically 177 of the Playwork handbook explores further training
Best wishes
