How to mark Selenium+Python CheckBox?

Question

Python

Good day!
I am writing autotests, or rather I am just learning, I ran into a problem - I can’t click on the CheckBox accessing an element not by FULL XPATH

When accessing by ID - driver.find_element(By.ID, 'userregisterwelcomeform-agree_contract').click()
by name - driver .find_element(By.__name__, "UserRegisterWelcomeForm[agree_personal_data]").click()
on css - driver.find_element(By.CSS_SELECTOR("label[for='userregisterwelcomeform-agree_contract']")).click()
element not found
FULL XPATH only - driver.find_element(By.XPATH, '/html/body/div/div[1]/div[2]/div/div[2]/div/form/div[4]/div[1 ]/div/label/span[1]').click()
can be ticked...
But the task is that, ideally, the call should be by ID, but not in any case (find_element(By.XPATH, '/html/body/div/div[1]/div[2]/div/div[2 ]/div/form/div[4]/div[1]/div/label/span[1]').click())
Please help the experts!
Thanks in advance!
