Should I use breadcrumbs when they are valid on only a few pages throughout the website?

I am currently working on a website that does not have a lot of content. I've read that breadcrumbs should be used when there's 2+ levels of content. In my case mostly there are just two levels - home page and its subpages. But then there's Support subpage which then redirects to its subpages, so we have: Home>Support>FAQ.

I am wondering if I should:

1) use breadcrumbs just when there are more levels to the content (at the expense of consistency)

2) use breadcrumbs throughout the website, so it's consistent, although there would mostly be Home>Blog or Home>Contact which is not really good, because those subpages have their own headings, so there's gonna be information overload

3) not use breadcrumbs at all, even on those 3-steps subpages.

Personally I am leaning towards the 3rd option, but I've been struggling with it for a while now, so I thought to reach out.

Thanks!
