Whenever I compile my TeX file, I get the following warning
Unused global option(s) [english]
and
Underfull \hbox(badness 10000) in paragraph at lines 27-28

Remove \FamilyProcessOptions[]{TEST}\relax from your code. These keys of the family (keys with empty family memember) are set by \FamilyProcessOptions[.myReport.cls]{TEST}\relax before the keys of the family member .myReport.cls.
You could use \FamilyProcessOptions{TEST}\relax. Then the keys of the family are set, followed by the keys of the family member .\@currname.\@currext. While myReport.cls is loaded, .\@currname.\@currext represents .myReport.cls.
Here are two suggestions depending on what you want to do:
\begin{filecontents}{myBase.sty}
\ProvidesPackage{myBase}
\RequirePackage{scrbase}% <- added
\DefineFamily{TEST}
%\DefineFamilyMember[]{TEST}% family itself -> can be removed
\FamilyBoolKey[]{TEST}{inheritedopt}{TEST@inheritedopt}% inheriteopt is key of family TEST
\end{filecontents}
\begin{filecontents}{myReport.cls}
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{myReport}
\RequirePackage{scrbase}
\RequirePackage{myBase}
\DefineFamily{TEST}
\DefineFamilyMember{TEST}% <- define family member .myReport.cls
\FamilyBoolKey{TEST}{classopt}{TEST@classopt}% classopt is key of family member .myReport.cls
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{scrreprt}}% pass unknown options to the parent class
\FamilyProcessOptions{TEST}\relax% process family options and options of family member .myReport.cls
\LoadClass{scrreprt}
\end{filecontents}
\documentclass[
inheritedopt=true,
classopt=true
]{myReport}
\begin{document}
\makeatletter
\ifTEST@classopt
classopt=true
\else
classopt=false
\fi
\quad
\ifTEST@inheritedopt
inheriteopt=true
\else
inheriteopt=false
\fi
\makeatother
\end{document}
or
\begin{filecontents}{myBase.sty}
\ProvidesPackage{myBase}
\RequirePackage{scrbase}% <- added
\DefineFamily{TEST}
\DefineFamilyMember{TEST}% <- define family member .myBase.sty
\FamilyBoolKey{TEST}{inheritedopt}{TEST@inheritedopt}% inheriteopt is key of family member .myBase.sty
\FamilyProcessOptions{TEST}\relax% process (family options and) options of family member .myBase.cls

Other example (regarding the update in the question):
\begin{filecontents}{myBase.sty}
\ProvidesPackage{myBase}
\RequirePackage{scrbase}% <- added
\DefineFamily{TEST}
\DefineFamilyMember{TEST}% <- define family member .myBase.sty
\FamilyBoolKey{TEST}{inheritedopt}{TEST@inheritedopt}% inheriteopt is key of family member .myBase.sty
\FamilyProcessOptions{TEST}\relax% process (family options and) options of family member .myBase.cls
\ifTEST@inheritedopt
\RequirePackage{showframe}
\else
\Ifundefinedorrelax{KOMAoptions}{}{\KOMAoptions{paper=landscape}}
\fi
\end{filecontents}
\begin{filecontents}{myReport.cls}
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{myReport}
\RequirePackage{scrbase}
\DefineFamily{TEST}
\DefineFamilyMember{TEST}% <- define family member .myReport.cls
\FamilyBoolKey{TEST}{classopt}{TEST@classopt}% classopt is key of family member .myReport.cls
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{scrreprt}}% pass unknown options to the parent class

This really depends on the class you're using and/or your document preamble, but you're probably calling
If the (global) option
englishis not used by the<class>it is passed to and package you might load along the way. If TeX reaches\begin{document}without theenglishoption being used, it'll issue a warning and reference all unused options.Typically
englishis used withbabel, so you can addto your preamble for
englishto be properly used, or remove theenglishoption altogether from loading the class.Your second question is addressed here: What are underfull hboxes and vboxes and how can I get rid of them?
