I would highly recommend a PROMPT intro course especially if you plan to do any motor speech work. Justine Rhind is brilliant and the PROMPT trainer for the uk.
It is very useful for helping to identify when motor speech might be a problem and how to treat difficulties in children as young as 18 months. The bridging course is also excellent teaching about the conceptual framework and using a holistic approach to rebalance a child’s system for more optimal communication.
This is the one training that had the biggest impact on my practice especially when entering private and beginning to work in early years.
Best of luck and sounds like you r had loads of good advice!
