Monks read sutras at funerals to explain Buddhism to bereaved families and those attending.
It explains how to respond to the death of a close person.
This is also an offering.
They are called law-enforcement and fearlessness.
Also, when believers give money to the principal image or monk, it is an offering, called wealth.
Financial aid is not limited to this case, but also includes offering money, goods, etc. to people in need. For example, fundraising, donations, or volunteering also contributed labor.
If you want to receive the reward of this donation yourself, it will be your own joy, and if you hope that the deceased will receive it, it will be the joy of the deceased.
If you turn to everyone, it will be everyone's joy.
I don't know the story where the Buddha didn't receive an offering, but the Gaki Jikyo also describes how he received it. Also, in the Hakku Sutra, there is a saying that generosity is a stain on those who give blessings, and that people do alms according to what they believe in according to their purity and joy, so I think the offering itself was recommended.
However, in the Gaki Jikyo, there is a story that if you don't give an offering to someone (monk) suitable to receive an offering, you can't get that reward.
Therefore, I would like to work hard so that we monks are suitable monks to receive alms, so that we can become monks to the extent that you want to give alms.

It also depends on the denomination, but the sutras read in the Jodo sect are written about how to accept death. That's why I recite sutras at funerals. It's just Chinese, so you don't understand the meaning even if you listen to it. Therefore, I will explain the contents of the sutras during the memorial service. Sometimes sutras are read in easy-to-understand Japanese, meaning a written sentence.
Also, it is often said that Buddha doesn't write about what happened after death, but that's not the case. For example, the Dharma Sutra left by Buddha in oral tradition says, “Those who make bad things feel sad here, they grieve smartly, and they both grieve together. Seeing his dirty behavior, he is sad, and he is worried. Those who make good things rejoice here, rejoice smartly, and rejoice together even though they are both. He enjoys watching his pure behavior, and he is delighted.” There is such a thing. “Here” is interpreted as the present world, and “kashiko” is interpreted as the next life. It may be convenient for leading the Buddha's people, but I think it's okay to follow the Buddha honestly if it's convenient for him.
