I am currently dabbling in Python in combination with Selenium. I can't get any further at one point.

Enclosed you can see three screenshots. At

econ-button btn btn-primary are actually 3 class names.
By.CLASS_NAME gets only single class name parameter.
To work with locators containing multiple class names you can use By.XPATH or By.CSS_SELECTOR.
As for me both the above methods are good, each of them having several cons and pros.
So, here you can use

browser.find_element(By.CSS_SELECTOR, 'button.econ-button.btn.btn-primary')

Or

browser.find_element(By.XPATH, "//button[@class='econ-button btn  btn-primary']")

Generally, you can use By.CSS_SELECTOR or By.XPATH. No need to utilize By.ID or By.CLASS_NAME since they are actually internally immediately translated to By.CSS_SELECTOR or By.XPATH :)
Some people preferring to use By.CSS_SELECTOR while others prefer By.XPATH.
As I mentioned previously, each of the above 2 methods having cons and pros.
For example you can locate elements by their texts with XPath only. XPath supports locating parent element based on their child nodes.
On the other hand XPath will not work so good on Firefox driver while it works perfectly on Chrome driver etc.

The element Zu den finanziellen Angaben is a dynamic element. So to click element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:

• Using CSS_SELECTOR:

  WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.econ-button.btn.btn-primary[value='Zu den finanziellen Angaben']"))).click()
  

• Using XPATH:

  WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@class='econ-button btn  btn-primary' and @value='Zu den finanziellen Angaben']"))).click()
  

• Note: You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
