What are the best visa options for a family looking to stay in Thailand long-term?

Hi everyone! I am posting anonymously as my work situation is uncertain and I do not want to share it with colleagues and others who know me.

We are a family of 3 and I am currently on work visa while my partner and child are on dependent visa. We are looking at plan B options as we want to remain in Thailand for another year at the bare minimum. So, I am reaching out to you:

1) if anyone tried the Long-Term Resident Visa (as highly skilled professional) and could share your experience?

2) which visa options you tried in a similar situation.

Any advice would help at this point
