Short answer: yes, look for a local estate planning attorney.
I work in this field, and I am also unmarried and childfree. I have a trust based estate plan.
My beneficiaries are other family members and/or friends.
What you are probably seeing with regards to couples/families are examples that cater to those because that’s the majority of people.
But don’t assume that estate plans are one size fits all and you will have a “square peg round hole” situation just because you have no kids or whatever.
Unless you DIY on legal zoom (please don’t), they’re highly customized to your situation.
So just because you don’t have kids…
— you probably have a desire for other people in your life that you’d like to inherit your assets (or charities)
— you probably want to make the above process as easy as possible for your loved ones
— you probably have in mind a person you’d like to appoint to talk to doctors for you if you’re incapacitated… or pay your bills and handle your money for your benefit if you’re incapacitated.
Generally — be weary of generic advice you might get on the Internet (like here) and do go to a local attorney to discuss your specifics.
