3D animated Instructional Designer/Technical Writer with niche experience seeking advice

Hello technical writers of Reddit. I was a 3D instructional designer for over 5 years, making around 100k at the end, which involved taking existing documentation, videos, and references to make step by step detailed animated instructions with text in my ex-company's complex proprietary software (so it transfers nowhere).

The industries we worked with ranged from flat pack furniture assembly to garage door opener installation + wiring, and later on helping large manufacturing companies with internal training (Siemens for example) and even the US military. We had a set of writing standards we followed and rarely did anything copy/paste from the references we were given. Either misspellings, inconsistencies, or certain products not having anything written at all required us to make most of the written instructions from scratch. In addition we almost never had the necessary SMEs to meet with and get details from, we just had to "figure it out" and hope what we sent over for review was correct so there was a lot more to this job than making animations and copying existing text within the available documentation.

I want to fully transition to technical writing and feel confident I have the skill set and years of experience for a pivot like that to not be impossible, but want to know what I should focus on? I know a lot of technical writing positions are for API/software documentation which I don't have experience in, but I know there are other sectors that need writers for more procedural documentation, like utility companies.

The question for you experienced folks is if you were in my exact position, what industries would you be researching + types of samples in your portfolio to stand a chance of getting a good (70k plus) job offer?

Thank you for reading my wall of text, any help is greatly appreciated.
