Put the data into a dictionary

    mydata_dict:
      my_host_name: myvalue
      default: default value
    mydata: "{{ mydata_dict[inventory_hostname]|default(mydata_dict.default) }}"

For example the playbook

- hosts: my_host_name,my_host_name2
  vars:
    mydata_dict:
      my_host_name: myvalue
      default: default value
    mydata: "{{ mydata_dict[inventory_hostname]|default(mydata_dict.default) }}"
  tasks:
    - debug:
        var: mydata

gives

ok: [my_host_name] => 
  mydata: myvalue
ok: [my_host_name2] => 
  mydata: default value
