Have you asked past bosses, co-workers for referrals?
Edit: misunderstood "referrals" for "references" so edited my reply out. No, I've never asked for referrals from past colleagues.
From where I sit, it's a tool for marketers and recruiters to gather data and it's otherwise completely useless.
YMMV. White collar work here follows connections and introductions - nearly exclusively. A few of my clients might have poked around Linkedin in passing but most have never used it.
As an aside, I deleted my LI because I've never had a legit contact thru it, only spam.

Absolutely ask for referrals. You gotta painfully get on LinkedIn for maximum effectiveness -- if you're looking at a company and an ex-coworker you got along with knows someone there, ask for the introduction. It feels awkward and weird but it increases your chances somewhat.
I strongly recommend you show your CV to someone and get feedback.
I am not the original commenter but I think something that younger people forget is that when you reach 2 decades or more into your career, your network starts to dry up for you. This is in addition to your skillsets and work cultural fit being suspect because of your experience and age (set in their ways, old thinking, etc…).
I have been in tech for nearly 40 years. Almost every one of my former bosses is either out of the industry, retired, or dead. My network is useless to me. If my current job ends…I won’t find another tech gig.
I've been developing for over 25 years and my early bosses are almost certainly retired but I still have connections from back then in colleagues that are still wording I could reach out to. Unless you stopped interacting 40 years ago you should still have current people regardless of time in the industry.
Current colleagues and bosses would have to cycle out themselves and land elsewhere before they will be a help as a network resource.
Also, for current colleagues—-consider the case if your whole team gets RIF’d. At that point they are no longer your colleague, nor really a good network resource until they land. What they are is a competitor and a competitor likely similarly skilled as you, competing for the same roles that you are.
Your best network resources don’t currently work with you, but are secure in a gig, and someone you have worked with or for in the last 3-5 years.
